Bug description
When both EasyVillagers and Aurum's More Blocks are installed, the Lectern cannot be placed inside a Trader. Likely cause is AMB overriding the Lectern recipe to allow for more variants. Issue does not occur with AMB uninstalled.

Steps to reproduce the issue
Install EasyVillagers & Aurum's More Blocks
Craft any Lecturn (including "Default"/Oak
Right click on a trader
Lectern will not be placed in the trader

Expected behavior
The Lectern is placed in the trader

Does their lectern work with vanilla villagers?

For all of the woods expect Oak, yes.

Jungle

Oak

So, my mistake- could be an issue with AMB, not EasyVillagers. I had seen some Spawned Librarians with Oak & made an assumption, sorry =/

No problem :)
Just report this to their issue tracker and let me know if there are any problems.
For now I'm closing this issue.
