I dont know what happened, but there were 2 times already that i found my team has been been deleted. 1 time no monsters were in there (reset), and 1 time a copy of an other team apeared in there (2 spots, copy paste).
I didnt want to do it, and have no idea how it happened. I just played a pvp match, after it I changed to an other app (didnt close the app, minimaized), and when i opened the game again my team was gone. I didnt even entered the build team screen, so i dont even think i clicked unintended.
Devs, please fix it, even get rid of these buttons, its so anoying when it happens!
