Thank you for flagging this up Eric, and thank you Lollorian for posting the Tsujatha fix! I've updated the download file with the typo corrected.
I've tried replicating the Ajantis bug but can't seem to get it to happen at my end - I've tried on vanilla BG2 and BG2EE, using Ajantis v12 and v13, and it's installed OK. There's a check in the Faren tp2 that should only install the Faren-Ajantis ToB content if ToB is installed. So I'm not sure what's going on with that I'm afraid!
If you could post your Ajantis debug file as Lollorian mentions above that would be great. I can't spend very much time on the computer at the moment because I'm very pregnant and have a lot of back pain, but will try to keep in the loop!
