Win 10 - GOG BG2:EE w/ ToB also installed:
In the underdark using the Big Metal unit with the Drow Illusion causes 2 bugs. One is that if equipped, the unit works but the image does not change...I.E. the character stays looking like a Drow. Perhaps that is intended.
Second, I "was" using the unit OK in the mind flayer section of the underdark but it was causing a second of lag when equipping the BMU. Also, even though I still looked like the Drow due to illusion, I could not walk through doors and it appeared that pathing was clunky. I summed that up to the game was pathing me as though I was a giant golem even though my character looked like a drow.
Once I left the Flayer section equipping the BMU caused the game to crash, and pretty hard. It would hang forever until I ctrl+alt+delete, and the alt+tab to bring up the opened program tiles so I could click the "X" on the BG2 box to close it. The "Hang on while we send this to Microsoft
" would open and sit forever, forcing me to click cancel to get back to desktop.
Also of note: Reloading back to the Mind flayer earlier save still caused the crash, it was sorta like the game said, OH now that I am aware of this illusion Frow thingy, I will no longer allow it and puke even though it DID work originally.
Then I reloaded to a much earlier save, back in Amn graveyard (random loc but I wanted something outside) and the earlier save allowed the BMU to work find and with even the lag when equipping it.
I am using EE Keeper and the Tweaks pack. So ya some mods. However i do not
have the mod/tweak that removes the drow paperdoll change...so my characters do in fact look like the Drow.
That's all I got for now.
TY for any insights and perhaps you can find out what's up and get corrected.
