Dear Jastey,
I am here to report content compatibility issue between DSotSC and VC. Found in VCv10 and DSotSC v3.0 beta
VC's component "Improved Shadows and Shadow Dragon (by Vlad)" modifies ICBONE01.cre creature - Bone Golem. It empowers it significantly adding immunity to normal and magically enhanced weapons up to and including +3. Also it makes such golems immune to elements, magic damage and poison. Howewer in DSotSC there are a couple of places where bone golems are present.
Due to that fact that this is BG1, party could be at approx. 10 level and there are no +4 and better weapons (no more Daystar, but even if it would be in place, party is too weak to use it for killing golems), such enemies are unbeatable. See more details here.
It looks like this could be fixed or workarounded. It could be detected by MegaMod installer and VC10 component skipped, but Imp proposed better solution.
Bone Golems in DSotSC could be moved to another CRE files, so any mod that empowers bone golems won't affect them. Moved - having complete separate copy of original CREs distributed with the mod, not just copying original to override in installer, because VC will be installed earlier.
