recently updated to 10.8 for minecraft 1.19

after doing so, if I kill a mob while invisible as soon as I am no longer invisible the mod reappears.

is this a setting or is this a bug?

if it is a setting, how do I change it?

Sounds like a bug- I assume you mean from the Cloak spell?

correct, I'm referring to the Cloak spell.

How are you killing mobs?
I have tried with spells (which instantly cancels Cloak) and with a sword, neither brings the mob back.

Can you provide some specific steps that get it to happen for you?

This does sound like a bug that I had a long while back, but it should've been fixed and definitely shouldn't have come back somehow in 10.8

If you can help me reproduce it I can probably fix it, but so far I am not seeing the issue.

I'll give a full explanation and do a video screen capture showing it once I get back home... out of town till July 6.
