[1.21.1] occultism dictionary causes modonomicon spam errors when opened

[ryeisonline]

Describe the bug
When we open the dictionary, it lags a bit and the console sends a long paragraph basically saying that opening the book causes an error in the server about how it doesn't save correctly.

To Reproduce

1. Get the dictionary for the occultism mod
2. Open it or browse through the pages
3. Error on console

System (please complete the following information):

• Modonomicon Version: 1.21.1 (latest mod version on both occultism/modonomicon)
• OS: mac
• Minecraft Version: 1.21.1

@ryeisonline can you provide the full debug.log?
It seems that the occultism modonomicon book is not loaded, but the reason for that would be earlier in the log.
It seems this is a fabric/(neo)forge crossover pack, so it is likely that is related to the issue, but with the full log it might be fixable
