Do Not Stack Lava Lobster Traps
I stacked two of my Lava Lobster Traps and they instantly became just Lobster Traps. They maintain their coloration but no longer say "Lava." I did separate them to see if that reverted them back to saying "Lava Lobster Trap" and it didn't. Consequently, I do not know if they will work as LLTs or not. Don't risk it.
