I was using the mini-display that you can enable that acts like a minimalistic version of WAILA and I learned the semi-hard way that it crashes and soft-locks your world as it attempts to render thaumcraft jars with the sticky attribute and placed in any way but facing up (geomancy feature); the issue doesn't occur if you turn it off

The world soft-locks as long as the render of the UI is enabled

How to Reproduce:

1. Download Thaumcraft and Gadomancy
2. Start World
3. go into the NEI settings and enable Highlight Tooltips
4. put a warded jar in an arcane crafting table along with a slime ball (this will make it sticky and is vital to reproduce the bug)
5. place jar at an angle on a block anywhere except the topside of the block
6. upon it being highlighted the game will crash
