World temperature detatched from seasons, ozzy liner bugged

[Huebs]

So it is mid summer on my server and we are in a plains biome. However, we start to get incredibly cold when outside, to the point of hypothermia during battle towers and stuff and are constantly having to light campfires to not die. So we decided to craft some ozzy liners, but they are also bugged out. Ill be sitting in my house completely neutral temperature, but once I put on my ozzy liner chestplate, it starts lowering my temperature more and more and more until im on the stage next to hypothermia and my screen is super frosty. What is happening? Could my seasons somehow be unsynced and its actually winter temperature despite it clearly being summer on the seasons calendar and outside? Why is the ozzy armor not moving me towards neutral temperature? Any help would be incredibly appreciated

Use heating and cooling coils.
