Ahh. In that case, I will do some process of elimination to see if I can reproduce this in different circumstances reliably. I'll get back to you when I know more. Thanks!
[edit] First thing I tried was to just start a fresh game and it definitely happens right away. I thought maybe it was circumstance.
That being the case, it's got to be a combination with some other mods I have installed. I'll run some tests and figure out what the minimum required mods are to make it happen.
[edit2] Hrmm. Well that was unexpected. First thing I tried was only to have this mod and HISHS enabled. No other mods. Fresh game. Open inventory, bots are there. Press SHIFT-B twice and bots are deleted. That's odd since you tried it and that didn't happen. Thoughts?
