Collide Callback multiple times problem

[Your Computer]

anyone?

I desperately need the info as I want to gift the full conversion to my boyfriend as christmas present on friday and the only thing that doesn't work are the collide callbacks..

Why wait for a response? Part of creating a story is trying and testing things out. The game will save certain script mechanisms during the game session and afterwards when the player decides to save and exit: this if the script didn't request for removal upon being triggered. Unless you want things to repeat, setting collide callbacks (and other kinds of interactions) in OnStart is the practical method.

If you want other people to test your work, you can request for testers.
