there has not been any news of ntt 9945 since around 9944. yal (yellowafterlife) seems to work on it for a week or 2 every few months (probably between paid jobs). he seems more invested in getting a stable gms2 version of the base game (with 60fps) than pushing a new stable ntt build. but that requires contacting rami to push steam updates which isnt the easiest thing to my understanding. but i dont really know anything. he posts in and checks the 2021_beta_bugreports channel in the nt discord. you can ask there or tweet him i guess.
