Yuyu and I discussed this yesterday and we agreed to add the fog event. Being the fog is specifically for a mini biome.Maybe you don't have to scrap the previously planned fog weather type, as it could be possible that the fog seen in the 1.4
spoiler is only happening in the new graveyard minibiome, which is created by placing many gravestones next to each other.
I could be wrong, tough, but it would make sense if its biome specific, as the fog started after the scene became a graveyard,
if I remember correctly.
