Hey @gozerKeymaster,
I’m using 5.0.3, trying to make a “flag” using this, and ticking those two options crashes the editor. In fact, I think its the “Collide with Environment” that’s the issue, I can tick that, press play, engine crash with this error message:

I’ll be honest, I have no idea what the issue is, so haven’t been able to resolve it myself.
Any info would be appreciated.
