Upon starting a new dedicated server, the world is generated but crashes shortly after a connection attempt with:
A single server tick took 240.00 seconds (should be max 0.05)
(I increased the max tick time from 60 seconds to 240 seconds just in case, but it didn't help)
I can reproduce this issue every time when I use a seed of 8675309
. Changing the seed did seem to help.
