Vehicle Issue – Performance Upgrades Not Saving

Hello,

I’m experiencing a recurring issue with my vehicle where performance upgrades are not being saved.

I purchased a maximum transmission upgrade and a maximum engine upgrade, but after buying them and parking the vehicle, the upgrades disappear. This has already happened twice:

• First time at "Harmony" garage

• Second time at "Benny's" garage

Both times I paid for the upgrades, but they were not saved on the vehicle afterward.

It seems like the performance parts are being removed immediately after purchase/parking.

Thank you for looking into this.
