Searched and couldn't find this reported: hard crash with the Improved Shapeshifting component of SCS during BG2EE Chapter 5 once your party has been transformed into drow. Specifically, this is with the druid HLA elemental shapeshifts, although I also tested with a few of the regular forms as well. Running SCS, Ascension, IR+IRR, & SR, and Tweaks Anthology.
