Hi!
Server keeps telling this:

[14:24:48] [Server thread/ERROR] [co.te.bl.Blame/]:

****************** Blame Report 1.16.5-3.3.0-forge ******************

This is an lengthy report. It is suppose to automatically read
the JSON of all the unregistered ConfiguredFeatures, ConfiguredStructures,
and ConfiguredCarvers. Then does its best to collect the terms that seem to
state whose mod the unregistered stuff belongs to.

Possible mods responsible for unregistered stuff:
