I am assuming this is mod-related but can't figure out what mod. If I disable all mods and clear cache it works fine. I turned the mods on 1 by 1 checking the t series by spawning a different car and then a t-series again. It still worked when I turned all of the mods on and switched to a different car and back to the t-series using replace current vehicle. Once I close the game and log back in the problem is back again. If I clear cache with mods on the problem remains. I included a list of mods I have downloaded and a photo below. Does anyone know what the issue is?

also narrow your search down only to mods that affect the semi. enable some of the mods, clear the cache, then restart the game. then repeat that until you find it.
I enabled mods in groups of 16 writing them down. I found a group of 20 that caused the problem. After each test, I closed the game and cleared my cache. I then went to 8 mods of the 16. No issues in that group so I tested 4 from the other group of 8. No issues so I tested 2 from the remaining 4. No issues. I went and tested the last 2 and had no issues. I think it might be a combination of mods and not one single mod. The last seen error occurred in the group of mods listed below.

I was having a similar issue, and after looking through what mods installed we had in common, I've discovered it's the D-series addon. Deactivated it, cleared cache, and the T-series is back to normal.
