Outside of the end of the round, the incrementer just works normally. It keeps the player limit 2-4 higher than the player slot count, with delayed downticks. If there's a bug in the game with these increases, it would need to be addressed differently.
This is exactly what I'm saying. Once you fixed the black screen issue with the end of round increase, this new error showed up. At above 32 the increment stops working properly.
But I should test it with the new patch and see if we experience anything different.
