Several bugs have been reported about the array.
1, Entering and exiting the nether gate will cause the array lead to be cut off.
2、When entering the nether gate, sometimes the location information is not correct and the gate is passed by itself.
3, When you go far away or enter a nether gate and come out (location information is updated), the lead tied to the fence is broken or the lead disappears, or there is a very low probability that the array is dead or gone.
This is all that has been confirmed, but there will probably be more due to the "location bug" in the array. Please resolve this issue as soon as possible for the sake of the arrays.
