• all mob farms not including a spawner are broken and will not spawn any mobs.
• I spent a few hours today making what was supposed to be an amazing mob grinder but nothing spawned on it. I did a lot of research and found that I in fact placed everything correctly its just that the way mobs are spawned now is so messed up now because this version is shared with mobile users whose devises cant handle as much as a console. Because of this the algorithm for mob spawning has changed and is all sorts of messed up so there is no possible way to actually make a mob grinder now. Personally I dislike this as a mob grinder is one of the first steps in automation in this game. Also I still don't understand why they are pairing up devices that can handle large amounts of work load with devices that cant and then they optimize the game for those who cant handle the game, not those who can. From what I gathered from my digging is this is due to realms and the fact that the better together update allows mobile users to join the console players and when they do they would crash if they were forced to perform at the same level as the consoles. The only real fix I can see is to separate these devices and make the console versions of bedrock more similar with the java edition because lets face it a xbox one or ps4 have just about the same computing capabilities as a $500 gaming PC.
