Some modded cars not having wheels or tires after update 0.20

after updating to 0.20, a bunch of my cars don't have tires anymore, and then I go into the parts selector, and it just removes the wheels entirely. This post is technically about mods, but they were working fine before the update. I haven't seen anyone else with this problem.
I've also tried everything I could think of, using a beta version of the game uninstalling all other mods, uninstalling the game, validating through steam, but the problem persists. Would appreciate any help

 

actually..everyone is having this problem and a lot of mods are outdated for now..it's not really a beamng staff problem..the mod's creators need to update the mods for the last version
btw this happens because some things have been relocated..so the tires for that vehicle are in a new location that is not set in the mod

 

Try and add them manually in the parts selector.
