Theres many acheivement where it wants you to grind certain things in multiple games is a bug. for example the "smelt a total of 1000 iron ingots" resets everytime you change server. or the "spend a total of 10min" resets too when u change server. I'm pretty sure you don't have to accumulate these in just 1 game since there is'nt "in a single game" in the sentence. bug?
it just means that u have to complete that achievement in ONE game of anni, its not for EACH AND EVERY game of anni
Theres this acheivement Blast furnace where u need to smelt x ores in a single game and ground formation where it says you need to smelt a total of x ores. This clearly means that you can do the acheivement throughout multiple games but for me that ground formation resets
