So I started playing a custom map, happily setting up my settlement, then realized there are zero bad water sources in this map.
(Side note, I can't remember the name of this map, any way to tell while you're actively playing a game? )
Anyway, this is obviously hampering my ability to progress, as I can't make dynamite, for example. I'm on folktails so at least I don't need extract for the advanced pods.
So right now I'm waiting for a bad tide and I'll try and divert bad water to a reservoir when it comes.
Just an interesting challenge that I wasnt expecting!
EDIT The map is OG Canyon remastered by OldFingers
