If there is something wrong with the mod, or me personally want to do something about that, the delay is minimal. I am playing periodically so yea... it can take month, but most fixes are released even before someone notice, cause i will notice on my save when playing.
And to my experience, mods i used as templates were hella complicated for no reason causing specifically me some performance issues... That is why i started managing this mod, where i have all the code from my own hand... Nothing fancy that is slowing the game. Just pure feature, easy as it can be done. I think...
