So I wanted to try my game on my computer(it only has the first level sort of done except for ai), but for some reason it failed and as I am new to unreal, I am not really familar with what would cause it to fail.
In the log file, on almost every line, it says there is not enough space on disk. That might be the cause.
I tried closing my web browser and a number of other things and it worked, so it must of been a lack of memory.
