Alright, so after I compile a map using these settings, os_tool build-cache-file-ex test levels\test\test

it creates the files and whatnot and I can play the map etc. If I continue to compile other maps with the settings 1 1 1 and then go back to play that map, it just crashes, is there something I am doing wrong? can someone please explain to me? Is it because it is overwriting the data_files?

Dont make data files

do 0 0 1

and then it won't load and it crashes, however I believe to have figured it out, 0 1 1

that way it doesn't create a new and adds it to the data files and uses the memory upgrade. I believe that works, haven't tested it yet. will soon.
