Hello, I would like to have the date of the wipe in 2021 that I know to notify my community vis a vis my server when it will start all over again approximately (in months if there is no exact date) because I have been told that it was almost every three months, but I don't know when the last general wipe took place, best regards.
All you can do is wait for the next update to drop and see if they recommend a wipe or not. They don't generally tell us ahead of time, and they frequently won't know for sure until after it's been tested in the experimental branch. 1.6 just dropped on the experimental branch. That is the next update. At this point in time they have not yet recommended that a wipe will be 100% necessary. It is expected to reach the stable branch in 2 weeks (but might be delayed, depending on what gets found in experimental). Even if a wipe is recommended to get the new content, you can usually still keep your old save if you choose. You just might be missing some of the new content or you may have to visit a new unvisited world to get it.
