Hi, not a clue unfortunately, but the reason I'm posting right now is we had the same issue in October, first time I ever witnessed that.
The last time it was something occlusion related for us.
Now again after the Christmas patch on 18th we wiped, it started to happen again, to some players.
Players entities and i/o connecters like you mention, pipes and so on or cables and switches, sometimes boxes even construction, parts vanish and dissappear compeltely from sight.
It was patched out previously, at the moment I have no idea what to do sadly.
For reference we run the Oxide frame work in a Linux environment and it only occurs when the server is restarted.
Did you notice is it only on restarts, or can your reproduce the problem?
Looking into a solution.
Merged postWe'll be testing removing server occlusion grids from now on, it seems like its either directly causing an issue with players and / or most definitely some plugins including networking problems / also because some plugins may not be well udpated in regards to networking the correct data to clients etc.
will be trying to add to the script .sh if on a Linux machine o the .bat batch file in a windows environment
either way, adding -disable-server-occlusion to the startup script will remove the grid from being generated, this hopefully will alleviate these problems.
Please don't do this during a wipe without testing, I don't know if it will invalidate your save states.
