tolua++ dbcall failed!: [string
“–shared\functional\SANDBOX_DATA\CCarCalculat…”]:146c attempt to index field ‘EngineInfo’ (a nil value)

what were you trying to do when it gave this error?

Attempting to open the sandbox part of the game itself

Can you try removing your latest model from Documents/Automation/Models and see if that works?

Yeah, this happened to me. I just deleted my latest car (because it bugged out) and it went away.
