Issue SMAPI Not a crash but loops until you exit

[OronTheNoldo]

An error appears only when you host a server not always but some thing like 75-80% of time

[13:51:39 ERROR game] An error occurred in the base update loop: NullReferenceException: Object reference not set to an instance of an object.

Thanks for the log, it looks related to FarmTypeManager. Maybe one of the mods that depends on it is the issue; you can try removing a couple of those temporarily to see if it helps.


But, I see you're also missing the Error Handler mod from SMAPI; which helps fix some bugs.
Redownload SMAPI: https://smapi.io/

Extract it; then go into the SMAPI 3.18.2 installer/internal/windows/ folder, and extract the 'install.dat' file.
Go into the extracted folder, and copy the "ErrorHandler" mod from the Mods folder back over into your own Mods folder.

Already done so, loop show not so often, but still remains. I wonder why in single player it runs perfect, but in multiplayer it appears? I mean it appears when all is loaded and after server starts, on the start of new day.

Unfortunately, I'm not really sure. Probably a good question for the mod author.

FarmTypeManager does store its own per-save data in its own folder. Under the "data" folder.

So you could always try deleting those files to see if it resets this weirdness.
Though, you may want to back them up first; just in case it works. That way you'll have something that can be investigated further.
