Description (Required)

When I try to merge 2 items into an anvil the cost is not the same after putting them in an Auto disenchanter. It does not keep the repair cost.

Steps to reproduce the Issue (Required)

Expected behavior (Required)

That the auto disenchanter does not remove the repair cost.
it should use the RepairCost nbt of the previous item, and add them to the result, so it cost as much as before to use in an anvil
