Hey I am on my first serious run, downloaded the game in September. Now, I want to start playing around with faction camps and saw that there have been a few fixes/upgrades to them and wanted to update the world. Is this possible or do I have to start a while new game each time I want to update?
Update whenever. Things might break, things might disappear, things might change; just revert if the difference is game-crashingly bad. Change your tileset by going to Settings -> Options -> Graphics -> Choose tileset.
