TIME PUT TO TESTING: UNDER 5 MINUTES [VERY UNSTABLE]
This plugin now only contains 3 base weather types: clear, rain, storm. Other weather types were put away for now, since people were complaining. Once this gets released, you'll get an extension called ProperWeather-Weathers (which is currently being worked on) which will contain these funny, annoying and fancy weathers.
Got rid of integers as weather IDs, we're now using strings, as integers are unreliable...
Got rid of WeatherManager class, which had a lot of old, deprecated code
Removed compatibility with extremely old save files
Preparations for custom weather elements, custom weather cycles :)
This is alpha(testing) version, so it's unstable, but contains new features :)
Reloading the server may result in several problems
