Hi,

i am running a 1.15.2 Vanilla Server on a Mac Mini. Previous Versions ran perfectly fine. Me and my friends just started a new world yesterday and we noticed a huge delay when leaving the server.

We click on "Disconnect" on the client side and it takes about 15-20 seconds for the Player to leave on the server side. When I hover over the player counter in the server list, it shows my Username as online in this time and i am standing in the world. We had some problems like "emergency logout" because of creepers, but they exploded because the player did not log out correctly on the server side.
