Can't cure small hides, but can cure any other type.

For some odd reason I can't cure small hides, only medium/large hides.

This is intentional, as there exists no recipe that uses small cured hides. Previous versions allowed players to cure them, only to later discover that they completely wasted both the hides and the fat. So the curing recipe was removed in 1.14.

Ah, gotcha. Thanks for clarifying. ^^
