By doing "who need friends" tasks, I played 3 games against an offline friend. First played one, then other 2 as rematches.. Then returned on my island and was idle for a while and after returning had that message that shows up when your idle, turned it off and went for 4th, last game against a friend.. Then game stucked on spinning globe, and after I hitted refresh, reinforcements bar was full, I had all used weapons back and I lost some ~4k coins that I won on those 3 games in which I had loth of luck killing enemy worms :(

It reseted 3 games which tucked ~10 minutes O.o

Towelie, only users from friend list are counted. If you battled against someone from buddy list, it won't be considered a friend.

No, it reseted games totally, like they never happened after I refreshed page, and it was not just 1 game, there were 3 games.
