Just survive

Does anyone remember when H1Z1 was just 1 game? and it had two game modes? survival and battle royal? but then the devs decded to split the game into 2 other games, and then start working on them seperetly. In the past month i was enjoying a nice new type of survival on the offical just survive server, then a few days ago they changed it back, can the develpopers not make up their mind about what kind of game they want?
