All right, my NEW problem. It's the Companion Share feature. From what I could get from Morrowind Scripting for Dummies 5, I just need to set Companion to 1. I did this. I also checked it against the line used with Calvus, the mercenary in Tribunal. It was right.
So I've added the following:
Set Companion to 1
AIFollow Player 0 0 0 0
When I play the game and get to this segment of the dialogue, it comes up with the following errors:
Syntax Error Line 1
Could not find variable "Companion"
==> CompileAndRun problem was found in Topic "travel together"
"Me? Ready? I'm always ready. That's the first thing an adventurer learns on the field."
Any ideas... ? I'm about to recompile all the scripts, but seeing as I didn't (afaik) add or change a script, recompiling them shouldn't change much.
