Invalid Simulate Options

I’m not sure what this error means:

Invalid Simulate Options: Body (BP_Checkpoint2_2.Mesh SM_checkpoint) is set to simulate physics but Collision Enabled is incompatible

This error appears very sporadically, so it’s a little hard to troubleshoot.

The only thing I can think to change is WorldStatic to WorldDynamic. I’ve set that and its working so far, but only time will tell.

What generally causes that error?
