Minecraft Version

1.21.1

Immersive Engineering Version

12.0.0-182

How did it happen?

While playing the modpack "TNP Limitless 8" on version 0.24.0 (latest one), claiming quest rewards for the Immersive Engineering questline gives 2 blueprints that crash the game when hovering over them. This is unrelated to Sodium, since removing it and its addons causes the same issue, as you can see in the crash log.

This looks like they give you invalid blueprints, or at least use invalid data when showing them. I will add a safeguard for that case.

Not sure if I should reopen this issue or open a new one so sorry if I chose wrong, but I'm still getting this crash on 12.1.0-185 in Ocean Block 2 (still mc 1.21.1), also going to link the Ocean Block 2 issue for it: FTBTeam/FTB-Modpack-Issues#7049

(The creation of the invalid blueprints had nothing to do with IE, but they still shouldn't cause a crash by simply existing)

New issue please.
