Every once in a while, on the private hive, vanilla server that I play on, and also on official servers, I have experienced that the entire base disappears. I have observed, in the past few days, that this effect only affects certain areas at a time. All barrels/tents/walls/etc. at the cargo area of berezino disappeared after a restart/crash, but the barrels/etc. at the western edge of Berezino was not affected, and vice versa. Farming plots do not seem to be affected.
The frequency of this seems quite random, but with a couple of restarts every day, I have seen it happen twice in the past four days on the part of the map I have frequented.
The community on the server are constantly complaining about this issue, and it has already and will continue to cause player fatigue over time. The grind feels pointless.
