not entirely sure whats going on here, any insight?
I'm getting this weird string of errors regarding the crossfade?
"MC_POST_UPDATE" from "Reactions Port Pack" failed: resources/scripts/main.lua:470: bad argument #2 to 'MusicManager_Crossfade' (number expected, got nil)

Thank you for the report!

This seems to be a problem with the function that tries to restore the music to it's original state once the reaction is disabled, however it returns nil and so it errors out since it cannot play a track with index nil.
I suspect that because you are getting this error the Reaction Music is not being removed when it should (unless you go to another room).

Questions:
Were you using Soundtrack Menu when this error occurs?
Does this happen even without Soundtrack Menu?
