Don’t know if Ludia reads this - but just did the update and doing the trials. Noticed that when a player can’t be found and it asks you if you want to play a bot instead they seem to have changed the mechanics. My highest level is 14, I have a couple level 13 characters and one level 12. Three times in a row when agreeing to a bot I get 3 level 14s and a level 17 . . .
Wish they would fix that but in the meantime I would advise people not to take the bot and waste your gems.
