@Alienscar i tried your tip of going back and seeing if any levels were missed and it had missed 12277 and jumped to 12278 so i completed 12277 and now my avatar has caught up and jumped to level 13340. Thanks so much.
one day I was in the 20s wiith my boosters and the next I was at 99+ and it’s stayed like it for weeks and also my avatar is stuck and won’t move to the level I’m at now.
