Sakul.CRE has an item SCRL1R in his inventory; looks like a typo as it doesn't exist.
This one is dud? BG1UB changes SCRL1J to SCRL1I. So, if you haven't made a typo, another mod is doing this.
pretty sure i didn't make a typo, so if there is any other mod that's doing this, then it's likely BGT.
this is what
Sakul's inventory looks like in NI with just BGT 1.07 installed. maybe this resource isn't being copied over from BG1?
a couple more minor questions/typos while i'm at it:
1. bg1ub/dialogues/u!minor1.d
REPLACE_TRIGGER_TEXT %JAHEIRA_BANTER% ~"Kahlid"~ ~"Khalid"~ //5, 8 (line 17)
%JAHEIRA_BANTER% evaluates to BJAHEIR (according to g3_bgt_cpmvars.tpa) but the misspelled "Kahlid" appears in BJAHEI.dlg, not BJAHEIR.dlg
2. bg1ub/BGT/baf/act13.baf
CreateCreature("_HALFEN2",[-1.-1],0) // (line 11)
creature doesn't exist. even if %tutu_var% was placed in front, there is still no HALFEN2.cre
3. bg1ub/BGT/spl/bgwi924.spl
the 'play sound' effect looks for a missing sound file WERE_01 (at 0x10E). maybe it's WEREG_01?
