It is the second tine it is happening to me. the first time i thought that maybe i clicked “surrender” by accident, but now it’s happens again.
i fly weekly challenge. i was at 81 level, i clicked “end session”. i tried enter game again. i saw strange error massage and clicked OK. i again click game icon. entered game - and wasn’t at mission. all my progress GONE. and it’s second time this is happening!
