Custom Map crashes

[Luqkim]

Hi, i have a problem playing Custom maps on Battlefront.

I can't seem to load some of the maps I installed, the game would go to the loading screen and ultimately crash back to desktop.

I still can play some maps, but most of the maps I downloaded have this problem, and I really want to play them.

This happens in Instant Action as I only play Singleplayer.

Is there anyway to fix this?
