They don’t appear because the enemies you’re supposed to kill for the bounty aren’t there because they’re overwritten by plague enemies. When the area is corrupted, both the enemies and the icons reappear (I’d prefer the enemies to appear anyway, even if the area is corrupted).
I’ve always complained about this, it doesn’t make sense that if you change the position of the runes I have to destroy the 2 runes and put two new ones, and I have to pay 4 times
I really like your post this topic I added it to the LIST of Great TOPICS that DEVS should see
