Several Players Affected by "Bugged" Pity Rates on Crossing Void Banners

Like in may Gacha games, Dengeki Bunko: Crossing Void has a customer-protecting failsafe or "pity" system in place. These are introduced so players can reasonably expect to get a character after pulling a certain number of times. For Crossing Void, this is 91 pulls per banner, or featured rate-up character. In other words, the 91st pull is guaranteed to be the featured character.

Obtaining a character other than the Limited S-Character will +1 Lucky value; obtaining a Limited S-Character will reset it.

(Lucky Value of Limited-Banner increases the Drop Rate of the Limited S-Character)

Lucky Value is shared by all current Limited-Banners and can be carried over to subsequent Limited-Banners.

The in-game text above explains it in terms of a Lucky Value (number of pulls without an S-Rank) and Probability or Lucky Value Bonus. This value states that on the next pull, there is a 74.30% chance of getting the character.

The pity rate is intended to rise on the way to 91 pulls so that some players will get the character before 91; the guaranteed pull is usually meant for those who are less lucky. After 91 pulls, the rate is reset and starts climbing again for those trying to pull a second copy. This is where the issues have been occurring. 

For the past few banners, there have been inconsistencies with the pity rate's implementation versus how it is displayed in game. 

Reddit user Sonaharu posted an imgur album of Gacha pulls with a maxed probability rate. The series of images shows pity rates before and after pulling six characters-- none of which are the featured one, despite the 98% drop rate.

This isn't the first person to have bugged drops, either-- several users have noticed this happening as early as the 12th of December across multiple banners.

This may seem like typical bad Gacha luck at first. However, the probability of missing a 98% chance this consistently is astronomically low. It's like flipping a coin that lands on its edge, standing up-- then flipping another coin, which also lands on its edge, on top of the other coin. Multiple times.

It's clear by the rate at which the displayed "Probability" rises that the average player (or whale seeking dupes) should get one copy every 90 pulls or so. But by the looks of it, the displayed Probability rate rises too quickly in-game while the actual drop rate-- hidden to end users-- is different. This is clearly shown by numerous users getting no drops at 99%, while relatively few pull the character before reaching high pity. 

I'm affected by this, contacted a Staff member on discord and the response I got was "I've checked your account and you already have an Alice" and "it's probability".I clearly specified that I was trying to pull for a dupe for awaken materials.I did however end up getting it 2 pulls after taking these screenshots - 165 pulls in total after first S Alice...https://imgur.com/a/PUUORU7

Just for reference (1.50 + Lucky Value):
126 pulls is 20.30%
149 pulls is 41.80%
153 pulls is 53.30%
163 pulls is 83.30%.

So I got to 99.5 like the previous bugged post on this sub. This makes me wonder if the pity system is real or if they are just gambling that we will get the character before we hit 169 summons, which is the top end by the way. I’m reporting this to customer service. I’ll let you know what they say.

Note that one user had to contact support-- and got the character right after sending a message. This also happened in another instance brought up by user KwanMeng:

Nothing above would be too unusual for Gacha games, since mistakes do happen regarding probability and drop rates. However, for those games (one example of Love Live: School Idol Festival comes to mind) corrections were prompt, even going as far as to take down the banner in question and prevent any more faulty pulls. 

Reading the Tweet made by Crossing Void's global team, it becomes clear such measures were not taken-- instead, the onus is on players to seek compensation.

We've detected that a few Void Agents are bugged due to abnormal account status and fail to obtain the S-Alice they should've summoned in time.

If you think your account experienced the same problem, please contact us in-game via [Settings] - [Customer Service] - [Contact Us]. 

"Abnormal account status" is strange phrasing-- does this mean only certain players have falsely displayed pity rates? How does anyone know if their account is abnormal? In any case, spending and pulling on banners is very discouraging. Having a 10-15% boosted chance for an S-rank is usually tempting, but after this, users have no way of being sure if the drop rates are actually as advertised.

Most likely, 91Act (the pubisher) did not count on users sharing their pulls or comparing results to the degree they did on social media. While one case of missing the 99.5% chance is easy to shrug off as bad luck, multiple reports are enough to raise suspicion. 

What's worse, 91Act has control of the official community channels, so complaints or speculation that the pull rates are being deliberately manipulated have been censored or dismissed. While we can't tell for sure that the inconsistent rates are manipulated or false advertising, the lack of transparency is disappointing. 

In any case, falsely advertised Gacha rates are punishable by law, so the bug needs to be fixed and soon in the interest of earning the trust of players. Nobody wants to play a game this stingy, especially with so many other titles right around the corner.
