Version: 1.9.4 4019 Mode: any Seed-Id: any Reproducibility: always Severity: broke build Type: API DemoMod Repro/Summary: In Visual Studio, if you build or rebuild the post build steps (delete output target/copy build to active game content/mods) fail because the directory path contains the hyphen in "/Empyrion - Galactic Survival" ... adding double quotes around the path parts of these commands solves the issue. change this: del /F /Q ..\..\..\..\$(TargetName).dll copy /B /Y $(TargetPath) ..\..\..\.. to this: del /F /Q "..\..\..\..\$(TargetName).dll" copy /B /Y "$(TargetPath) ..\..\..\.." There is a related issue on Windows systems that the default Steam root puts the game tree inside /Program Folders which has security ACLs that prevent non-admin traversal of the tree- a comment about this and work arounds either in the program or the yaml would be helpful.
