A user admin contacted me about this due to a ticket that was filed, so I figured I'd also post here:

I'm going to work on scheduling a point of time that those are active where they won't conflict with other things. We can't have them any time outside of just Survival, because the hexes for Morostide will also mess them up. There are a few things on that system that are named different things (hexes, kisses, infections etc) that work the same.

We will not retire the achievements. I'm just working on a solid time to have them available. :)
