Don't exactly were to place this, so in combination with what's going on at the moment, I place this here.
I have a good neighbor from the beginning, and a good gem giving member. But i don't know if it has anything too do with what is going on lately, but I think he left the game?!
From yesterday on I couldn't give him a daily gem anymore

And I thought let's give him a visit. I was shocked to see I could tap the invite button.

So this means we are no neighbors anymore, that's explained why I couldn't give him a daily gem. I will not believe he deleted me from his list. So I assume he just decided to leave the game. I did invite him back to see if i get a response, but I'm afraid he left, and raised every neighbor. So sad. Is this the beginning?
