Description (Required)

Ok so my server is having some issues:

1. Every time someone uses an explosive pickaxe the durability of the one showing in the sf book goes down.

2. When the durability reaches 0 the item dissapairs from the slimefun guide but can still be pressed on

3. All explosive pickaxes on the server starts dropping only the one item u mined but it still mines in 3x3 but u lose all the other resources
   Is there something that is wrong on the server side and if yes how do i fix it. and if its not the server should i report it?

4. Restarting the server temporarily fixes the issue as the explosive pickaxe is back in the guide and works but the durability goes down again so it stops working when it runs out. It seems like the durability on the explosive pickaxe in the guide goes down by the amount of blocks broken so if i hit a wall and it breaks 18 blocks then the durability of the pickaxe inside the guide goes down by 18

5. I noticed a similar report in #question channel on the discord

From what i can see: mine using the explosive pickaxe until the explosive pickaxe in the guide is gone/out of durability

Expected behavior (Required)

The durabilty of the explosive pickaxe in your hand to go down when using it, but not that the explosive pickaxe inside the guide gets used. Also expected that the items in the 3x3 drops when mining before and after it is gone from the guide
