I have stopped playing frequently for the simple reason that I am already witnessing a bug in some four versions and report on this site and you never fix it. This bug is about the caves because as I said about four versions ago I can't find a cave entrance and I suspect that either the cave entrances are gone and you added caves submerged in water without any connection or proximity to the seas and rivers or is occurring the simple problem to which all cave entrances are filled with water, thus ending up with dry cave entrances.
