Hi, looks like SCS causes a CTD when entering AR3022 (Watcher's Keep -- Anti-Paladins).
Tested this using vanilla BG2EE (Steam) and installing just
// Log of Currently Installed WeiDU Mods
// The top of the file is the 'oldest' mod
// ~TP2_File~ #language_number #component_number // [Subcomponent Name -> ] Component Name [ : Version]
~STRATAGEMS/SETUP-STRATAGEMS.TP2~ #0 #5900 // Initialise AI components (required for all tactical and AI components): v32 RC5
~STRATAGEMS/SETUP-STRATAGEMS.TP2~ #0 #6000 // Smarter general AI: v32 RC5
Also, removing GITH03.CRE, gorgit.CRE, OHGITH03.CRE from override directory does "fix" the crash so this might narrow it down a bit.
RC4 is also affected (caught it there first).
