Topic category: Troubleshooting, bugs, and solutions
I have already asked about this on Help with Modding (Java Edition), but, asking/reporting here seems more appropriate. Awhile ago, I have encountered (along with a few others) a bug where while teleporting between two mod dimensions (a weather enabled to a weather disabled), while it was raining in the weather enabled dimension. The rain would transfer to the weather disabled dimension and couldn't be cleared using /weather clear nor stopped within the hour and a haft of letting it run (I tried this in two different worlds using mod commands and a block to teleport, and both resulted the same). I checked if I did disable weather, and I did, then I checked if anything regarding weather was left in the weather-less dimension's code, and didn't find anything obvious (I am not a great java coder however). Then finally I rebuilt the mod, and it didn't fix it. This still could be an error caused by something I did, but, in case, I wanted to report here.
(Lastly, if this is the wrong place to report or if this has been already reported. I apologize!)
