Winter/Snow Icon over several buildings. Stretched to top/bottom of screen.
This is only on start of playthrough, when i disable the mod all my buildings go away but the issue disappears when i place the buildings again.

I suspect this might be a conflict with another mod. Could you share your mod list?

How would i be able to do that?

Also, Turrets are randomly "Frozen" even in summer.

You can find your mod list in the Factorio log file on Windows:

C:\Users\[user name]\AppData\Roaming\Factorio\factorio-current.log

For other operating systems, you can find the log file location here:

Open it in a text editor, search for lines containing "Loading mod", and paste those lines here.
