Yes I did initially try the antenna trick at first but that doesn't seem to work anymore - in fact a lot of people have commented on that video that the antenna no longer works - I suspect 1.4 had something to do with it
Wow thanks for the share! 😛 - this actually fixed it - how strange, this can't be intentional though
This is the mob spawner - as you can see I am y-160 - the mob trap is at around 184 - there are no mobs spawning.
Okay so I built another grinder - this time I built the collection area at Y-160 with a 24 block drop above (at about 184) to kill the mobs - what's weird is that I will get about 8 mobs falling and then after that it just stops.... I have tested this in both singleplayer and multiplayer (with only me on the server) and same results...
I guess the most frustrating thing about it is that I spent so long building and designing the trap just to see no spawns - I will include a picture of the mob trap above
Just updated to 1.4.5 today - this is a horrible bug 😞
