Just posted in the bugs section about this as well, yes I lost all my helpers last night after about 5 days of getting both the no server response message or the no Internet message, making it impossible to view my wall, friends or gifts! Sometimes, very occasionally it would come back and seem ok for a few minutes, then the messages came back.
Last night all helpers vanished then this morning I rescued two, one of which was an original one, but the other not. So far no sign of any more asking to be rescued!!!
Not sure what is going on with this game at the moment. I entered the poll, I'm level 182. Spent good money buying diamonds so if their intention is to p*ss off the higher level players and make them leave then that sucks, quite frankly!!
I opened a support ticket last night about all the issues (before I lost my helpers!) so might have to open another now about that!
One more point, since these issues started I have been able to send several chargers to people if they had them on their wish lists, hope they are not targeting me for doing that!! Never done it or been able to do it before so it's clearly another bug!!
