Considering they took what? 18 months to get from A16 to A17 you've got plenty of time before another update, at most you have another week or two until stable is released. Just an opinion, I would not go backwards to 16.2. There is a lot wrong with A17 but there is also a lot of good too. The dungeon houses, new POIs, the guns look and sound better (bring back parts if possible, that was always a fun part of upgrading weapons), trucks and gyrocopters. Please don't go back to circling zombies!
