We are finishing off a 40 min collab project, and in it we've realized that upon reaching 2,14 billion score, the score stops and starts counting backwards (even during breaks) in a slow pace. Once the map is finished you end up with approximately 1,3 billion score.

EDIT: Map link https://osu.ppy.sh/s/137839

Before the bug

Score starts counting backwards

2000 combo later, less score

It's probably never expected for you to have that high of a score. Since the number 2,147,483,647 is the maximum positive value for a 32-bit signed binary integer in computing (copy pasta from wikipedia for wording), it didn't go up, but went back down.

Yes, we've theorised about this and it seemed like a plausible explaination. However, I wonder if this will have any effect on ranking the map, because we've put a lot of time and effort organizing and mapping it for a year now. Our goal is obviously to get it approved.

unless peppy reprograms the entire game, or tries to work on a specific scoring system just to work around this 32-bit limitation, then no.

What Renevant said.
Dude nice.
Confirming & moving to Low Priority.

Edit: Auto finishes with a score of 695 516 816 on the grading screen.

It only makes sense that the score becomes less now, we've updated 2 whole songs more

I think moving back to high priority threads would be appropriate. Recently a beatmap that does exceed integer size was qualified (tho disqualified afterwards because of some issues, but is sure coming back very soon as it is now 2x bubbled). p/4624362

I agree
I didn't noticed it when looking at auto, but it is a big issue

Yeah honestly, I wonder why this Low Priority, it's actually quite a huge issue... The scoreboards will be completely messed up...

Because you can't have like 200 pinned threads.

Whether it's in the Confirmed (Low Priority) sub-forum or not basically has nothing to do with priority at this point.

I guess you could say that, yeah.

As I said previously, whether a thread was in Confirmed (Low Priority) or not didn't indicate its priority anyway, it was basically a useless division that served no purpose and only confuses people.

As far as I'm aware it was basically a remnant from years ago. That being said, Confirmed (Low Priority) has been renamed to Confirmed Issues, and all confirmed threads have been moved to there, and new confirmed threads will now go in here.

You may still see a confirmed thread pinned on the Help forum every once in a while for extremely urgent cases for awareness purposes, such as when there are server issues that people will rampantly report, but that would be the only exception to that.





Anyway, about the actual issue; According to TheVileOne this won't be simple to fix; There are many places that expect an int datatype that would need to be changed. There are possibly server side changes that need to be made as well.

I can't really say more than that about the issue itself as I'm not a dev.

It probably shouldn't be ranked until the problem is resolved.

Why not make a workaround for the issue, such as a new score calculation work specifically for maps that will break it?

I think it should be fixed, since there's a big difference in the score for my map https://osu.ppy.sh/s/150054
And I can't rank it for the moment...
It's around 2,200,000,000 (maybe 2^31)

The score just after the bug, and the final score

I just received word on this, and we're not going to support a datasize larger than an int. These maps may be setup to use scoreV2, but I don't think such a solution will be soon as that would be an equally sizable thing to give support for.

I would just like to say that The Unforgiving marathon currently can break the maximum score in CTB if someone were to FC it with HR (or HDDT, Abstract- is close to FC).

Or maybe someone has already done it but their score was low so we never noticed..

Have you not read the thread? There is a score cap because of what osu uses to calculate score and when you reach the max it counts backwards.

Also just because standard has no chance of being affected due to scoreV2 coming out doesn't mean this should go ignored as it was brought back up because of CtB, there has to be something that can be done to fix it even if it would just take the score and put a higher score on the leaderboard based on how much you got after hitting the cap or something.
