r22.5 WIP is now released to WIP backers via the Researcher Intranet. It contains the basics for LUA modding. It’s not full featured enough for any serious modding, as there’s only a handful of exposed functions, but it lets you poke around with the new modding tools and create code mods for the game.
Also, editing on the wiki was broken for some amount of time, but it’s fixed now. Sorry if you ran into that issue!
