Agreed - reset the boards. If you have to start us all at PR001, then go for it. You won't get a complaint from the players in our guilds.
Or perhaps we can reset all players to a Pirate Rank that matches their island's progress. A level 4 pirate hall with a PR of 100 and a level 7 pirate hall with a PR of 400, for exemple..
Need to show restraint in any resetting of ranks. There are honest players who have spent lots of money in the upper ranks. In my opinion, if resetting rank, reset everyone above 850 back to 850. I doubt anyone above 900 got there from attacking, only on defense.
I did not understand at once what spent. But afterward that seemed to me hallucinating. By reading this forum, I realize the problem. I can't wait that that does not arrive any more!
