My level designer is having issues opening levels in our game. Even in the packaged game, when transitioning to a new level his game crashes. In the editor some maps will open sometimes, but 95% of the time it results in a crash. I can post the log if someone needs it.
Any help???
Hey @Capn_C4ke!
Possibly! Logs would absolutely help! Specifically the crash log if possible 
Most of the cases it caused by corrupted assets. You need to read the log file to identify what is the cause. The log file will tell you what causes the crash.
Sometimes for my case, I had to delete the affected assets from the project in order to open the map. But, you need to know which assets are affected. The only way to know is to analyze the crash log file.
We ended up getting it figured out, if I remember correctly, it was something to do with a d3d device error. He said he had to go into RegEdit and and a string and value, and it all works now. I still have no idea what that all means, but atleast it works now
