Per @th3w1zard1 , co-author of pyKotor and HoloPatcher:
It's a rare unused feature of TSLPatcher that's off by default. HoloPatcher has it enabled. Basically tells you if a mod installs to a module directly (.rim/.erf/.mod) when it'd be 'shadowed' by a higher priority file existing in Override. See:
https://github.com/th3w1zard1/PyKotor/wiki/Explanations-on-HoloPatcher-Internal-Logic#the-patch-loop
Part of step 5.
In other words, a mod has injected a file into a module (MOD), but a file in the Override will supersede it.
On an unrelated note, why the hell is your game installed in the Users folder?
