Does anyone know if it is compatible with fcom? I'm doing a new install with fcom (hence the topics around) and I was curious. Referring to this mod : http://www.nexusmods.com/oblivion/mods/47211/?

Yes, it should be. FCOM's core is OOO, so it is possible that it makes changes to the same scripts, but I doubt it. The container scripts are pretty straight forward. Not a lot happening as far as references and such. There could be a key change or two, I don't know. When I say "key" I mean the thing you open locked doors with.

For now, I'd say yes. It should be 100% compatible. I'll verify that later after I open up FCOM.
