Infinity Expansion | Oscillators won't enable

[iRollNeed]

Description (Required)

I've installed Infinity Expansion and disabled some of the machines & materials for balance purposes to fit with my server's economy. Everything went well except the fact that Oscillators even though they are enabled, they won't appear as so. An error appeared in the console which I will provide below.

Steps to reproduce the Issue (Required)

Disable Advanced & Void Quarry + Infinity Recipes.

Expected behavior (Required)

As with any other item, Oscillators should have also been enabled and without any error appearing.

I deleted the items.yml file from the Slimefun directory and restarted the server. The problem was fixed after that.
