      Description

      Steps to reproduce:

      Do /gamerule randomTickSpeed 5000, then eventually it will crash. For the first time, I triggered it by pouring a bucket of water, but I can't reproduce that now.

      Expected result:

      The server doesn't crash.

      Actual result:

      [11:28:29] [Server Watchdog/FATAL]: A single server tick took 39.93 seconds (should be max 0.05)
      [11:28:29] [Server Watchdog/FATAL]: Considering it to be crashed, server will forcibly shutdown.
