First of all, i forgot to thank you for that thing with the Bank3Obj12 template, so... thanks.
I've got a different OCO-related problem now: I tried to replace the weird nonsensical helicopter-thingy on Bank2Obj24 with a weird nonsensical jetpack-thingy, like this:
...but it looks like this in-game:
(It looks like this on every frame, and only the black part is affected. Also, i did the same for Bank2Obj15, and it works properly.)
Is there any reason for why this is a thing? And is there any way to fix it?
