My monthly achievement for the survivor one is bugged as well, showing the same as the screenshot from the opening poster.
I’ve tried to accumulate a boatload of experience in a safe way (crafting, can’t die doing that) to see if it might fill it regardless, but I’ts staying empty and none of the tiers go up.
As I am planning to do loads of stuff with mystic coins i’m feeling slightly upset I’ll be missing out on the monthly achievement reward.
Please fix this before the month is out, so I can have a shot at completing it.
Bitter thing was, I had completed it before it decided to bug out.
