There are currently no known bugs or issues with the multiplayer beta, although I've only tested it two player with a fellow dev. If you find any bugs, definitely report it! Assuming there are no major bugs, I plan to push this build to the default branch in about a week, so everyone can try it out. I'll keep the beta branch available so you can access your beta saves (as the beta has a different saves list than default), but once multiplayer goes live, the beta branch will not be kept up to date.
As for what's next, I have a growing list of minor improvements and quality of life changes that I've been putting off while I finished multiplayer, so the next update will probably be a quality of life one. But after that, I think I'm going to start the magic path! I've already gotten a lot of models done for it, like the baby dragon below:

I hope you enjoy multiplayer, and are looking forward to the next updates!
