Crashing immidiately after chapter 2 movie/cutscene ends

Just starting a game with 6 custom chars (4 of which I imported from my BGEE game file). Immediately after the Ch. 2 movie/cutscene w/ Irenicus & Imoen at Cowled Wiz base, it comes back to Gaelan Bayle interior, and Crashes with a dump file (posted to the Support page).

I have installed in my game only the mods confirmed to be fully compatible from here: http://forum.baldursgate.com/discussion/23726/bgii-ee-compatible-mod-list/p1

I do NOT have Ascension, Item Randomizer, or any of the NPC or romance mods, and most of the bigger mods I only have selected components installed.

Obviously, SCS, aTweaks, and BG Tweaks combined take FOREVER to install/uninstall, so I want to eliminate all other options first before ripping my install apart.

Thanks for any help.
