Yep the collision/overlap-event isnt triggering, and i cant figure out why.
Nice, thanks for the input! sadly this just seems to give me more engine crashes 
investigating this function now tho, may get it working (will obviously report back if i do)
Any other ideas anyone? 
Edit: Just to confirm, nope, cant use RegisterComponent, that can only be used in the constructor of a UObject derived class, but i want to do it elsewhere (because it may not need the shape, depending on certain settings, so i need to do it only when its needed, ie; not on construct)
