Describe the issue

Game crashed randomly.

Steps to reproduce

• Playing in a single player world.
• Had 2 Building Gadgets inside a backpack from Sophisticated Backpacks, equiped in back slot from curios.
• No action related to Building Gadgets.
• Unable to reproduce at will.

Happened 2 times in a span of 3 weeks, so not very common, but it means I'm not that crazy.

Expected behaviour

Game should not crash.

Additional information

Reporting just in case it's helpful. Looks like EventRenderWorldLast.RenderLevelLastEvent is triggered incorrectly.

BuildingGadgets/src/main/java/com/direwolf20/buildinggadgets/client/events/EventRenderWorldLast.java

Line 30 in cedd338

((AbstractGadget) heldItem.getItem()).getRender().render(evt, player, heldItem);

Adding a type check before this line should prevent the crash, but real issue is probably somewhere else.
