Further Information

Steps to reproduce:

1. Equip Manaseer Monocle
2. Place a functional or generating flower
3. Place a Mana Spreader one block below the flower
4. Look at flower from above to see its aoe
5. The spreader doesn't render behind it
6. Replace spreader with any pylon
7. The issue persists

What I expected to happen:
The spreader renders
What happened instead:
It doesn't
(some other blocks probably have the same issue too)

are you using fabulous mode?

no, I am on fancy graphics

turned on fabulous, the blocks now render properly.

yeah unfortunately due to how TE rendering works nowadays this is unavoidable in non-fabulous mode. Fabulous is the "intended" solution to these problems.
