Hello,
I have a very strange issue when load a Realm:
Username: MoneyMattMatt
Realm: KermitCraft
Most of the time it works perfectly fine. Then sometimes while playing I get kicked out and cannot rejoin again. During the "Loading Terrain" phase, the terrain is not created (or half created) and after a while I get a connection lost error.
I have recreated this issue on different laptops.
I'm using my home wifi and during the issue internet access is still working fine.
Thanks
