The bug is still here on 5.3.2… This bug exist since 2014. WHY IT’S STILL HERE !? DO SOMETHING.
Same in 2024 with 5.4.1, it recompiles whole engine randomly when y are packing game, seems y can’t even rename folder with your project, it will do that.
Hmm the only “legit” way to do smth with it i found is in BuildConfiguration.cs of UnrealBuildTool, y can force to set bUsePrecompiled to true, tho y will need to do it manually seems like for any project after building.
public bool bUsePrecompiled { get; set; } = true
