Building Gadgets Version
BG2 v 1.3.8
OceanBlock 2 1.3.3

Describe the bug
I copied a fairly large cube, maybe 25x25x25 with the copy paste gadget. I put it in the template manager trying to figure out if I could edit the material list. I only want the stone shape, not all the misc modded pipes/machines.

I saved the copy paste gadget to a piece of paper in the template manager, then it crashed to desktop (CTD).
I reloaded the game, turned shaders off (I'm playing OceanBlock 2 1.3.3 modpack). When I reopened the template manager, it seemed to CTD when I hovered over the saved template.

I reloaded the game again, broke the template manager with a pickaxe and it seemed to crash again once I picked up the blue saved template item. Now the game crashes before even entering the world, I'm assuming because the item in in my inventory. I'm reloading a world backup to do further testing. :)

To Reproduce
See above.

Expected behavior
I was hoping to edit the material list and not have the game crash to desktop.

Screenshots
n/a

Log Files
I attached 2 of the latest crashes logs.

NOTE ON RUBIDIUM
Rubidium contains code that will crash many mods when used in conjunction with them. Unfortunately this includes Building Gadgets 2. There is absolutely nothing I can do on my side to prevent these crashes. If you're using Rubidium and your game crashes when rendering something, please try without rubidium before submitting a bug report.

OceanBlock 2 doesn't seem to have rubidium, I turned shaders off anyways during troubleshooting.

I reloaded my backup world to recreate the issue, successfully.
Here is a short 30 second unlisted video of the steps: https://www.youtube.com/watch?v=1pBPMKTWCjU

Basically I just want to copy the stone and air blocks of this "quadrant" to paste it in 3 other quadrants of my underwater base, to help me void water :)

As you can see there are plenty of modded items inside, and they seem to crash the render preview immediately.
I tried to copy to clipboard, so I could edit the modded items out, however it's blank?

• It crashes immediately when I click save, I expect because of the modded items render preview?
• I believe the copy paste gadget also crashes immediately if I switched it to paste mode, for the same rendering reason?

I just realized by scrolling down in the crash log, it was complaining about an ender tank.
Once I removed the ender tank, it's rendering fine, no more crashes! :) It's surprising only one modded block was the issue.

Client crashed for me as well using Cut/Paste Gadget in buildinggadgets2-1.3.8 on Ocean Block 2 v1.4.2 (latest) showing Rendering Block Entity issue java.lang.IllegalStateException: Missing elements in vertex: Color, UV0, UV1, UV2, Normal, specifically on the enderstorage:ender_tank (codechicken.enderstorage.tile.TileEnderTank) from EnderStorage-1.21.1-2.13.0.191.

It was a non-graceful handling of the entity resulting in a client crash and forcing a rollback of the server at TRANSFORMER/[email protected]/com.direwolf20.buildinggadgets2.client.renderer.VBORenderer.drawRender(VBORenderer.java:359) ~[buildinggadgets2-1.3.8.jar%23494!/:?]
