Perhaps if we could see the code for your Mover that is blowing it up, we might be able to help.
Especially right around line 50, where it’s crashing.
Hey there @dolphinstone! Welcome to the community! So as eblade mentioned it looks like one of your scripts itself is causing the error, once we see that we can make a recommendation based on it! That said it’s trying to access an incorrect memory location and the editor itself usually handles that. Are you using a direct pointer?
