Hoppers stop working or do not work properly

[Nat392]

Hello,

I've come to see you following several reports from our players who are reporting bugs on your latest version of your plugin (we're on the latest version of PocketMine 5).

We're getting reports that on server restarts, or just when the world unloads, the hoppers stop working or slow down (for example, we're getting reports that it transfers 1 item out of 2, etc.).

Here's our configuration:

# Define the number of ticks a hopper is on cooldown after pushing, pulling or picking up an item.
# Default: 8
hopper.transferCooldown: 8
# Define the number of items the hopper tries to push, pull or pick up when updated.
# Default: 1
hopper.itemsPerUpdate: 8
# Define how many hoppers are allowed to be updated every tick.
# Default: 0 (disabled)
hopper.updatesPerTick: 0

We suspect there may be a problem with the tiles, which have recently been modified.

Thanks in advance

We have been given these two examples (which are somewhat repetitive):

Good evening, the hoppers are blocked for no reason: either they don't put the items in the chest below or they don't retrieve anything. I can break them and put them back, but it doesn't make any difference. When one hoppers unblocks, another one blocks. And so on.

We also do it with chests. You have to remove some cactus and put it back or something like that and it's very embarrassing.
