What are some of the most updated mods?

OK so like a lot of the mods i try using ends up not being able to be used like extended buildings and some others do to what I’m guessing is the mod maker no long updating so i was hoping for some mods people use and know are being worked on.

That’s a tough one to answer. Dinomod, Magiclysm, Mythical Martial Arts, and Aftershock are all updated on the regular, but I don’t play current build so I can’t speak to others. For out of repo mods, check out TheGoatGod’s mod packs. Goat and the people who assist do a stellar job in keeping them up to date.
Regarding building mods, several of these were merged into the main game, but I can’t tell you which ones. Someone else can hopefully speak to that.
