Checking the Readme, am I right to assume that this component from another mod is already covered by NPC Strongholds?:
This is not something NPC Strongholds does, no, but it shouldn't be incompatible.
Kish, are both Oversight and NPC Stronholds compatible with BG2:EE, or if not do you planned them to be?
I really like to try them out some time, but I mostly play EE these days.
Unfortunately, I couldn't test them on EE, because I don't have it or plan to. I believe the only problems should be cosmetic (items which list who can use them twice, new journal entries maybe being disorganized). If you find any more significant problems, let me know and I'll fix them if I can do so while effectively working blind.
