When placing an Avaritia attuned crystal into a completed iridescent altar, or finishing building the surrounding multiblock structure with an attuned crystal inside the iridescent altar causes a crash.

Crash is caused by rendering block entity and I believe is caused by the mod trying to render the constellation on the ground but I don't know much about reading the crash logs.

This crash occurred even on a clean install with only Astral, Curios, and ObserverLib.

Steps to reproduce:

1. Create an iridescent altar and accompanying structure
2. Place an Avaritia attuned crystal into the top left slot (The one away from the crafting grid)

I've attached the crash log below.
