The mod converted successfully and works well (Megaton Return player house, BTW). When I try to open it in FNV GECK it aborts with a message that multiple masters were selected. But I've already deselected everything.
Does this have something to do with adding all those masters in FNVEdit prior to using the conversion script? I don't see any option in FNVEdit to remove masters.
So how is one to modify converted FO3 mods if not with GECK?
