I actually found many icon issues and fixed them in 2.12.10. The problem is the device database was storing the integer that referenced the icons but the icon resource integers can changes by release making the stored icon integer no longer reference a real resource. I now added a few checks but the most important one in the database itself where it makes sure only valid icon resources are returned. If an invalid one is stored, it will be replaced by the car icon.
