I'm making modpack, so I'm trying to make it so that weather only occurs in certain dimensions as well as disable the custom clouds to use vanilla ones. However, every time I change it in the config, the file simply resets itself or nothing changes. I've also noticed that the config file has old features that used to be in the 1.12 version (such as hurricanes), so I'm assuming the file was never updated. There's isn't any in-game config either so I don't have any other options. Would it be possible for you to update the config files to work with the most recent version? Thanks!

Same problem here. I even had some weird thing happen. I had my config files saved on server FTP and they got several times rewritten and saved on default settings without any command input. I found out when player reported to me that his base got destroyed. I set just "#leaves, #fire" to grabList. So I check my FTP and there are several changes. When I was testing config file and wanted to add #snow, it just did not apply the changes after server restart. /coro config reload common did not work as well.

As temporary fix I placed weather deflector on player bases so we can still play. It's such a cool mod but man, this issue is bad.
Also worth to note, this folder was empty of old configs. Server is restarted three times per day using Shutdowner mod.

Use Notepad++ to edit the configs. Save them as ANSI or UTF-8

These are not issues with weather2 but with NightConfig (forges config system). Maybe try configuring them at the main menu of your client and then uploading them to your server?

Edit: by main menu I mean go to Mods and then Weather2 and then configuration.

Fixed by CoroUtil 1.2.44. Please close this issue once confirmed. :)

this is still an issue for me on the latest version of the mod and coroutil available for 1.18.2, i change 'lockserverweathermode' in my misc.toml, and whenever the server restarts or i reload the configs by command it just resets my config change.
