Because sometimes (3 already) my recent created teams vanishes haha
I edit my teams (last time I edited about 10 new teams) and then when I go to battle it rolls back to the teams I had before ‘-’
Same here. Yesterday it happened on steam, and showed the old teams on iPad also. Today I had the problem on the iPad as well,without being on steam.
I also noticed that. Best way to work around it is to edit teams in the PvP screen, i.e. before fighting someone edit your troops in the team select screen.
