Help with tuning mod

Without having looked at the tuning files for GTS, I'd say it is highly probably that it's other factors that comes into play that makes the teacher walk over to the desk.

You kind of just have to follow the tuning (or script) trail to figure out what enables the teacher to walk over to the desk. It is quite likely it is related to the actual object resource key ID and not the object tuning itself. (You can get the objects resource key ID by converting the Instance Key found in your Object Definition from a Hexadecimal to a Decimal value by using the Hash Generator in S4S.)
