Still in pre release 2
Checked that in pre release 2 still happening
My server network just made a 1.14 pre release 1 server and have noticed the same thing it will constantly post the error Can't keep up! Is the server overloaded? and it will be running as low as 30-50 behind as high as 500 behind. Updated today to pre release 2 and still having the same issues. Its causing my players to not want to play on vanilla minecraft as they say its badly optimized and not playable. Please get on this issue as soon as you can its game breaking at this point.
For my server its almost as if the darkness is spreading it started with 1 or 2 spots around my base and now my entire island is dark and mobs spawn even during direct sun. Its been 3 days and the creepers are still there send help.
