the issues says "at TRANSFORMER/
[email protected]/com.hollingsworth.arsnouveau.client.container.CraftingTerminalScreen.m_181908_(CraftingTerminalScreen.java:144)"
Can provide full crash log if neccessary
Edit: tested with assigning the lectern to an empty container, crash still occured. I don't know what mod could be causing this, possibly EMI/JEI though I have been using those with ars without issue previously, so I'm unsure what is causing the issue.
The only ars addons I have are Ars Creo, Ars EC compat, and Ars Energistique (AE2 compat)
