Before updating to 1.16.1 one of the regions had Weather Lock Sun, when i updated that region turned to constant rain, even when i remove the weather lock flag, clear the weather, even with the plugin uninstalled its always rain now.

To Reproduce
Add region weather lock in 1.15.2
Update server + plugins to latests versions 1.16.1

Expected behavior
not rain

Additional context

weather-lock is entirely client side, it doesn't touch world weather.
if the issue persists even without the plugin it's not the plugin causing it.
