I was escorting Wulfram back to Cyseal and was half way there, did a quick save but happened to press it just as Wulfram got into combat. After loading then finishing the combat, he no longer runs back to town, he just stands there. When you click on him he just says, We can talk when we get back to town.
It's another example of (quick)loading messing with the AI's scripted routines. This is going to cause a lot of problems for unsuspecting players if it's in the release version, so I hope it's not too difficult to fix.
