Changing spec causes g-99 car to lose engine

On every character on my account, when i change spec, the ‘engine’ of my g-99 vanishes. Visiting D.R.I.V.E. and changing to another engine, leaving, coming back in, changing back, and leaving again sometimes fixes it, but not consistently. Happens on all characters, but i primarily play DH, noticed originally when switching from havoc to vengeance or the reverse. The boost button is a big red X and doesn’t work, says ‘not available’. Entering the DRIVE console shows it active. Reload does not fix, game restart does.

Using G77 Ultra, 22H slicks, Turbo Handcrank and The Buzzer.

Tested this using same options and default horn (Basic Horn), as well as Same options and default wheels (Tred-B-Gon) and it still happens.

Does NOT happen when switching between talent loadouts.

and what addons are you using?

Try disabling add ons. Rename add ons folder and cache, restart system and then try.

I can corroborate this bug.
