Building Gadgets Version
1.3.9

Description of Bug
Copied large structure that had lootr chests inside it and now game crashes when loading in.

To Reproduce
Copy large structure with lootr chests inside, switch to paste mode.

Expected behavior
I expected the copy paste gadget would simply ignore those blocks as they are not something a player can place down/interact with.

Log Files
Crash logs are extremely important in helping me figure out how I DireDerped.

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.
