@Ginger88895 It's been a few years, so I could be wrong, but as far as I can tell that callback does not do anything. It's probably something I added on accident and forgot to take out. When I comment it out, nothing seems to change at all (except for significantly less warning spam in the console). If I ever update this mod for Rep, I'll have to remember to remove it.

Is the callback added at line 447 intended?

It happens every run and I think that it might be harder boss patterns's fault.
It also could be Revelations but I'm not sure...
I have noticed that the game crashes once before you enter a boss (Satan / Isaac).

@the7screw I've tried several times to recreate this bug, but I've been able to continue every time on my end. Does this bug effect you on every run, or only sometimes? Are there any specific Mods/Items you have that might cause an issue?

A new bug: you can't continue after defeating Satan / Isaac.
maybe it's because I have too many mods installed but if it is true, please fix that...

Mysterious Paper has very weird behaviour with this mod:Isaac is switching between current animation and standing animation(it's even weirder with wings),but also when Extra HUD is enabled it shows Polaroid and Negative in first two spots constantly swapping positions with one another.

You're welcome, and thanks for adding me to the credits.

@the7screw Great idea! I've added it to the mod.

You know, to balance the negative I always thought it would be a better idea if it acted like the blank mod and removed all of the tears in the room...* an obscenely suggestive wink*

nice
