Not sure if this falls under the category of a botania issue, a new tardis mod issue, or a compatibility issue, so sorry if this is invalid/in the wrong place. When I equip the spectator from botania and look at the alembic, the game crashes. Worse, I can't start my save again, it just immediately crashes. I created a world to test this. Steps are very simple in creative:

Version: Minecraft 1.14.4, forge 28.2.5, botania r1.11-379, Tardis-Mod-1.14.4-1.3.1

1. Give yourself mana somehow (ex full mana tablet)
2. Give yourself a spectator and wear it.
3. Place down an alembic.
4. If playing singleplayer, the world can no longer be started.

The tardis mod is closed source so unfortunately there's pretty much no way to research the problem

Shame... hadn't noticed that before creating the issue. Debugging issues without source is a pain :/
I'll keep it open on their end, as botania is open source. I suspect it's an issue on their end anyway, with how the object represents its inventory (It has two screens which are probably what cause issues).

Was looking at the issue on their site and realized, if you're interested, it's not actually closed source. https://gitlab.com/Spectre0987/TardisMod-1-14/-/tree/master
