Issue
There's two issues
One:
It seems dying with the beetle pet on your shoulder makes you lose your armor but keeps your inventory.
Edit: I was wearing 2 armor pieces i got from the wandering trader before it go poof thanks to dying from the Crushers and the damned beetle laying on god knows where on my body.
Two;
The beetle pet doesn't seem to be there on your character after you pick it up and no way of putting it down.

Thank you for the report, I will investigate the issue.

Sorry if the explanation wasn't good enough hahahha. My explanation is that after you tame a beetle, shift right click it to put it on your shoulder and then dying with it on you causes no grave, armor deleted, and you keep your inventory. I'm also thinking that it deletes the charms/baubles you equipped too.

Well I was able to reproduce the no-grave part, none of the rest :)

To be perfectly honest I didn't fully understand you bug report, it's pretty confusing. I was not able to reproduce any of your issues, but did find another one.
