Currently on a new island doing the starting objectives. one of the last objectives for Iron Ore Mining isn't completing despite fullfilling everything it says to do
Here's a save where it happened. (Made a new save + loading it to see if loading fixed it. It did not)
Have you tried drawing your mining designation over iron rather than dirt/rock?
You might need to redraw the mining designation. If the designation predates the quest I've noticed it can glitch out and needs to be redrawn
Yeah, I did. (I double checked via the layers thing to make sure I was marking Iron specifically, and it goes very far into the mountain on that map)
even tried removing and readding the digger/trucks and no change
And yeah, I did remark the mining designation as well
