Wintergrasp Vehicles - Follow Breaking ?

using ISboxer mostly default wizard setup. So it has FTL and all that stuff built in.

Using the Wintergrasp Catapults, I seem to never have a problem.

However, Demolishers and Siege, they seem to follow for a bit, then just stop. I can't really figure it out. Typically, I am making sieges out of sunken temple, about 40 yards going up the hill, the slaves just stop.

I have also noticed if I dont swap screens, everything is ok. But the moment I switch screens and FTL, the other 2 enjoy doing circles :D

Just wondering if anyone else has had this problem, and any helpful solutions. Or maybe there is something I need to adjust in my setup.

Thanks,
Acid

I have this problem myself. I have thought about setting up a manually follow rather than using Jamba and ISBoxer to control it.
