Description of the issue:

Blueprints that were existing in 0.14-94, and the result of the crafting recipes now show a blank blueprint, that has no craftables from it in the engineer's workbench.

Versions & Modlist

IE 0.14-95
Forge 28.2.3
Modlist as per https://www.curseforge.com/minecraft/modpacks/kreation/relations/dependencies

Update; Blueprint as purchased from the Gunsmith villager also is blank.

Also having this issue. Blueprint item does not appear in JEI either.

I'm having the same issue.

Unfortunately, I'm not quite done with that yet.
