Geometry Collection loses collision and won't break in 5.6

Hello, i’ve been having a weird issue in 5.6, i fractured a simple plain static mesh with the uniform option, then when i place that mesh into the level it has lost its collision entirely and can’t even break it with fields from blueprints no matter what i tried. Impulse doesn’t work either.

I know this isn’t a lot to go on but any ideas will do, thanks!

Turns out the issue is that a fractured plane has 0 mass, and it won’t work once it becomes a GC.
I extruded the plane a little bit to give it some mass and increased it’s polycount a little bit and now it’s working as intended.
