Tip for epic about crashing

Ue crashed on me today 3 times when playing my game. Each time I only played for a few minutes then crash. Now I think the reason is because of groom. I had 1 groom asset with my player. Only 1 in the game world. I deleted the groom asset. Played my game for almost 15 min and no crash.
i think groom needs to be looked at.
Crash message said ue is exiting by d3d being lost

Ok i tried something. I put my groom asset back in. I changed it’s material back to the default groom material and played my game for 20 minutes and no crash. So I guess there’s nothing wrong with it.

Doesn’t make sense to me thou because I copied the default material to make my own.

Any way ignore this post i guess
