If you order your character to attack / interact with a certain NPC, and while it runs to it you try to attack / interact a different NPC, your character will continue running to the old NPC, and only after reaching it, will change to the new NPC.
Same bug for summons.
You won't see anything special on a video, just order your char to interact with some NPC and then request it to interact with another one and you'll see your char will not respond to the new request, it will continue going to the old NPC.
And that's what I did to fix it: https://gist.github.com/saharati/5de6975077f11f407e9a2116c8dde5ec
Written for aCis, import it. I gave it basic tests, basically I checked that it justs fixes the issue so I don't know if it causes any new problems, although I doubt.
can u post video please?
