Opening certain books -- for example, On the Dynamics of Integration from Integrate Dynamics, Force and You from ForceCraft, chronicle of Shadows_ from Apotheosis, but also many others -- causes the game to disconnect with the message

Internal Exception: java.lang.RuntimeException: Attempted to load class net/minecraft/client/Minecraft for invalid dist DEDICATED_SERVER

Possibly useful data point: If armor with Block Reach is equipped, then the disconnect occurs whenever one attempts to switch books, including back to the base Tome.

I'm currently on the Direwolf20 1.19 modpack, but I can reproduce this bug with only AkashicTome and one of the listed mods.

I could not reproduce this bug. If this is still relevant, please open a new issue and please attach a full log then
