Project counters get stuck and projects can't create new issues about sentry HOT 2 OPEN

The only other thing is that I assume the only way this can happen is via some kind of transaction rollback situation. Like:

• Event that would create group comes in, increments number, saves group, somehow project counter is rolled back (doesn't seem plausible since in transaction?)
• 2 events that would create group A & B come in. Due to some race condition, one commits later, or one rolls back, and somehow this breaks the counter (I don't have a solid mechanism for how this would happen)
• Something to do with merging/unmerging groups. We increment the counter on unmerge I believe, so this seems like a reasonable place to look as well. Maybe we don't handle transactions right there?

To test this theory out, we can look at Activity, with whatever enum values are merging/unmerging, to see if the timing works.
