Rewritten from scratch and updated to 99.5; this almost entirely fixes design issues as long as Lua is not involved. Stickmen might by crashy, I'm not certain.
New version released, this time with working stickmen and Lua scripts, in theory, which means that at this point, you can expect the same set of features without crashes as from vanilla. As such, I will be daily-driving this mod from now on, and I invite the more adventurous among you to do the same. Please report any issues with these features.
