For some reason All my projects would start failing to compile after the lines
Launching script compiler for new package scripts...
Command: E:\Steam\steamapps\common\XCOM 2 SDK\binaries\Win64\XComGame.com Arguments: make -nopause -mods XKanCAClass "E:\Steam\steamapps\common\XCOM 2 SDK\XComGame\\Mods\XKanCAClass\"
Log: Executing Class UnrealEd.MakeCommandlet
Shader map M_Digital_Distortion_Ghosting_A had an invalid uniform expression set and was discarded! This most likely indicates a bug in cooking, and the default material will be used instead. Then it would start to dump the fail and exit building. Afterwards, All projects including build in examples cannot be build and stuck at the same stage. I am able to temporary fix this by deleting all the built script under XCOM 2 SDK\XComGame\Mods and XCOM 2 SDK\XComGame\Script and start a complete clean. The problem is that it would come up time to time (I've encounter this 2 times for the past 3 days). And now no matter what I do it would build once and generate the built mod, and as I rebuild it the compile will fail at UnrealEd.MakeCommandlet Here is the full build log if the problem comes up : http://pastebin.com/8dq4Gq1Y and the crash log
