Hi, I'm trying to add a moving subobject that comes out from the ground in 0 seconds (Starting lights for rolling starts). But when I do a 'extra light' binded slider (or any other moving subobject), I get this 'BETA :sub has type 14 but mover has type 15' error message. I tried if its only an issue for object mods, but I tried making new object mod and it works fine. I'm trying to add this for my track mod 'N77 TRACK'. Basically, moving subobjects does not work in my track and shows that error instead. 
(It works in alternative version I have of the track, I guess it's just a 'mod specific' error or something)
