Describe the bug
RenderLib, or more likely, Entity Culling, does not get along with Grimoire of Gaia. Mobs are invisible and spam the log with errors.

Reproducibility

• I reproduced this issue with as few other mods as possible installed.
• I am unable to reproduce this issue consistently.

"Why not consistently?"
I cannot reproduce it in my instance inside MultiMC and java 1.8.0_441-b07
But a couple other players using ATLauncher get their logs flooded with these errors and cant see the mob.

To Reproduce

1. Install RenderLib and Entity Culling
2. Install Grimoire of Gaia
3. Spawn a Minotaurus
4. See error
   New:
5. Open a server, join as a client and do the above

Screenshots/Videos
No render, invisible mobs.

The part in specific, because the log got flooded by the error:

Edit:
I see now.
It only happens with clients in a server.
No issues in single player at all.
Took me a couple of hours to figure out.

Clients have RenderLib 1.4.3 and Entity Culling 6.5.0.
The server has neither. And, naturally, the server has nothing in its logs.
Servers are not supposed to have them, are they?

Works fine for me. (Server only has Grimoire of Gaia, Client has Grimoire of Gaia + EntityCulling)

That error means that somehow the data manager of that entity got corrupted. This has nothing to do with rendering and is very unlikely caused by EntityCulling or RenderLib.

Closing this now because there is no indication that EntityCulling or RenderLib are causing this crash.
