Lua error when switching from ladder to monocoque

I was tring to make an old design f mine monocoque top be mopre inn tune with the era…

When you say old, do you mean old as in pre1354-55? I don’t think those are at all compatible. Too many changes made during open beta. I had to delete all of mine from open beta.

old as in a 1966 car

From what game version?

Did you change the year or frame type or both? Does it error with only one or the other?

Frame type only

Which body style?

Does it do the same with every platform? Try revising a different platform and changing frame type.

no… only with at body type so far
