cant attached it to a char

hey guys i run multiple bots but for some reason today one of my bots stopped attaching to a character for no reason. we had a power cut and when i turned it back on all the bots worked apart from 1 and here is the message in the log.

i use the same honorbuddy client for other bots so its nothing wrong with the client and i use the same wow folder for others too.

Code:

[16:27:37.148 N] Honorbuddy v2.5.13860.786 started.

you might try deleting the settings folder for that character.
