Important Notes:
-
Never remove the base game .pak file — the app won’t run without it.
-
Ensure patch files follow the correct naming and sequence.
-
Patch upload sequence matters — higher numbered patches override lower ones.
Best Practices
-
Upload base game first, then patches sequentially.
-
Always retain older patch files before overwriting.
-
Ensure correct naming:
e.g.,testPatch3-Windows_0_P.pak,testPatch3-Windows_1_P.pak -
Removing a patch reverts the app to the previous version automatically.
