[2021] Is it possible not to have to perform a wipe on my server?

Options:
1. Don't update the server and have players not update their game.
2. Rename your server save files from the old version to the new one. Example: proceduralmap.4250.145905989.202.sav -> proceduralmap.4250.145905989.203.sav (changed 202 to 203). You'll need to do it for sv.files.202.db and player.states.202.db as well. No promises this wont break things.

Wipes keep things fresh and are very necessary sometimes due to changes made in the update.
