Compilation [ERROR] "Key already added" causing UI issues

[EzioTheDeadPoet]

Describe the bug

Compilation screen gets set to failed state while WJ continues on with the compile due to an "harmless/expected" error that isn't caught properly. This error might also be the reason why WJ doesn't properly delete temporary data during compilation resulting in the high storage requirement.
