Scripts from The Underground 2 .esp do not play (all patched versions)
Tested playing Morrowind through a wine setup with the same vanilla setup and mod files, and the mod works. NPCs, enemies, areas render just fine and can be COC'd into, but many scripts will not play (ie. Synda Rains will not walk to places she is supposed to during scripted events and will not operate normally as a follower, but just stands around doing nothing during the former and becomes permanently stuck in combat mode during the latter swinging her weapon at nothing). Most current Underground 2 patched .esp is attached (data files available on Morrowind Mod History, a very large download), but this was also tested with multiple updated versions of Underground 2 with the same results.
