I'm opening an A/Car tire template (or the subsequent vehicle assembly) and getting the following error messages during the "converting" process. The template/assembly is from a few years ago and I believe was working fine. I think this is a new message I'm hoping someone else has seen...
Are these dual wheels by any chance? _handling_tire template & testrig were updated a while ago (circa A2014) to support these. other enhancements may be playing a factor here too.
