Does this mean I can take my game out of beta on Steam and the saves from beta will work in the new release?
Yes.
Hi! Just killed the water elemental on core difficulty, didnt get the achievement. Is this bugged or cant we get achievements using the beta 1.1 patch?
Hello, achievements aren't turned on for the beta branch.
Is there a similar beta branch for Epic Games store?
Unfortunately not. They'll receive only the full patch.
where is it though?
Supposed to be fixed a while ago. Does it still not work for you?
If I start a new save on the Betatest 1.1. Will it get erased? Sorry if this is a dumb question
It won't be erased. But you may have issues loading your game if you go beta and then decide to roll back to the previous version.
