Firstly I would like to say I appreciate all the time and effort Sure AI has put into this wonderful mod. Encounters have been immersive, engaging, and sometimes I felt too much for my cowardly rogue. Unfortunately I've run into some hiccups with my stealth stabber:
When ghost walking I do indeed drop into stealth on the subject selected, however, the invisibility doesn't seem to proc. Other targets still see me and the target being attacked notices me after a hit and a few seconds. I'm not sure if this is just me misunderstanding the ability and the "invisibility" breaks upon attack.
Another issue, which can be slightly annoying, is when you're thrown an error message when trying to ghost walk. An invisible object that cannot be passed appears in the vicinity of the area where you would have teleported if the ability would have been successful. This has saved me by breaking AI for some of the tougher mobs but also has stopped me from running like a scared pit rat.
Lastly, I notice sometimes upon failure to use the ability my stealth will break causing enemies to attack and occasionally the targeted enemy lights up like an anti stealth christmas tree.
I tried searching the bugtracker and didn't see anything and didn't know exactly what category this fit into.
