This has been a problem for about a year (maybe longer? Soon or some months after Endless Mode was released), but if you kill a boss on Survival at any time before the end of a game, the camera freezes on the boss. Which has rendered a few custom maps obsolete on Survival and is kind of annoying when wanting to enable cheats in solo to test bosses.
With Endless mode, that isn't an issue obviously.
Some of the custom maps it's rendered obsolete in survival are ATAKA-Z (Now ATAKAV2-Z, by far my favorite custom map to play, where there's a 50% chance of a boss spawning with the wave) and Insurrection (at least solo, Insurrection has always been broken when playing with a team).
