I get a nice wall of Tickerror messages on my server after the update, this happens no matter what the server is up to. It even does it when the server is empty. I did notice some of the mods where removed compared to previous version so I tried adding it back, so far its only dooglamoojuniorarchaeology that Ive found missing. But it still lags. I did try running the same server with a freshly generated world and this made the server better than ever so its obviously something with the world generation or blocks being removed in updated mods or something like that, but I cant seem to figure it out. And since the people playing on my server do not want a fresh world (Cant say I blame them) so Im stuck with trying to figure out if I can get the current world up and running with the current update

Screenshot shows Opis from my client connected on my server with the server terminal through remote desktop in the background. The taskmanager shown is the server not my computer.

About 10 seconds later than the first screenshot, ping section of opis. This is on my local computer which is connected through the same switch as the server...

This is the problem Im experiencing, this screenshot is taken on an empty server.. freshly restarted none connected since last restart. Running with the same mods as before the last update

Did start the server with fresh world to make it actually playable, it still lags, blocks still reappears the tick errors come from time to time, but it is playable.
Are there more people that have experienced issues with the latest update?

I had similar problems, major FPS drops in some areas.

Try removing Opis from the mod-pack (client side). I know it sounds strange to remove the thing that can help you find lag, but trust me, it solved my problems!

I dont see how opis can be the problem as all clients lags both opis and non-opis. But the server is stabilized now as we have played up and explored alot of the world, it isnt until we start exploring that the server really starts having trouble.
Would like to ask if there is a update procedure available tho incase its me doing something wrong during updates, since it is then the issues seem to occur
