Describe the bug
RAT's Mischief lets you take over "Spy Rats" and control them. Whenever you stop taking over the rat, a gravestone will spawn at the rats location

Forgotten Graves Version
v1.19.2-3.2.2 Fabric (on quilt)

To Reproduce
Use both mods.
Craft a spy rat (eye of ender, rabbit hide, tamed rat)

You can tame a rat by feeding it then shift+right click to pick it up and use it to craft

Use the "Rat Master Mirror" to control the spy rat

Stop controlling the spy rat and a gravestone will spawn.

Expected behavior
No Gravestone should spawn

Thanks for the report!

I've resolved the issue and will be pushing out a patched 1.19.2 version shortly.

If you find that it still occurs at all please let me know, thanks!
