We are getting the same symptoms since the release of 1.52.

Server remains responsive to RCON but side chat doesn't go through (ie. it appears only on the screen of whoever sends the message), AI do not take damage, and RCON / in-game player lists do not update - both show players who have disconnected, and nobody can join. Players cannot be kicked or banned, etc.

Spectating other players shows them walking on the spot, yet according to their screens, they are continuing as normal.

I can see nothing in the changelog that may have caused this, but the problems never occured until 1.52.

FYI although these symptoms began directly after we moved to 1.52, through a prolonged period of trial-and-error we determined the "fix" was to wipe the database and start again. (we run Epoch) Attempts to prune the database with honestly-not-hacky Python scripts were successful in reducing the size but did not help in alleviating these symptoms.
