      Description

      Hello,

      I want to inform you that with Vanilla Minecraft 1.14 servers have a problem with generation. All servers of Vanilla Minecraft 1.14 have 20000+ms This problem is not with my machines. I tried with 4 other machines and the problem is global with 1.14. I asked other hosting companies and they have the same problem with Vanilla Minecraft 1.14 servers

      • On other versions like Vanilla Minecraft 1.13.X there is no such this problem.

      Console errors:
      -------
      [Server] Server thread/WARN Can't keep up! Is the server overloaded? Running 19877ms or 397 ticks behind
      [Server] Server thread/WARN Can't keep up! Is the server overloaded? Running 16605ms or 332 ticks behind
