Your Expectation

The "Soul Beacon" from Thaumic Horizons, when paired with a curative vat and an appropriately-prepared corpse effigy, is supposed to allow the player to reincarnate with the effigy as their new body. This is supposed to work even in hardcore mode.

The Reality

I created a curative vat. I created a corpse effigy, placed it in the vat, awakened it, and infused it with every available human infusion (10 unique infusions in total). I then placed a soul beacon atop the curative vat in place of the modified runic matrix, and bound myself to the soul beacon. I then sacrificed myself at a blood altar, to reincarnate into the corpse effigy. Instead, I received the hardcore mode "Game Over" screen, with the "Delete World" button. When I pressed this button, it gave me two new options: "Title Screen", and "Respawn". When I clicked the latter, the game crashed ( crash-2024-04-17_09.26.51-server.txt ). The save was deleted. I attempted to restore the save from the most recent backup, but I could not enter the save at all. I attempted to restart the pack, but I am now unable to start the modpack instance at all, as I receive a startup crash every time I try. The startup crash does not actually generate a normal crash report, so I have pasted it from the Prism launcher's error popup into a txt file here ( startup crash log.txt ).

Your Proposal

Fix the soul beacon so that players in hardcore worlds are able to successfully reincarnate, and so that attempting to do so does not corrupt the modpack instance.

Update to this: dying with a method other than the sacrificial knife (I used a cactus in this instance) works correctly. The sacrificial knife appears to be the cause.
