Additional comments:
This problem often arises. During 4 pit race, at the last stint on pit lane, previously setted type tire replaced by another previously not setted.

The same problem during offline races, but during online race you put the lock on the action in pit lane, so smtimes i can't change tire type. Pls do smth!
