I don't even remember when was the last meaningful update to this game, even Tesla made 30 cars in past 3 months! but, not a single good meaningful update from devs in that much time..they treat their game-coding at par rocket science maybe even higher than that because in last 3 months SpaceX made numerous successful launches but here we have NONE. The only possible answer i can think of is that devs must be working on some other project otherwise this is beyond my comprehension to grasp this fact that for so long we haven't seen an ACTUAL UPDATE.
