The chest implant patch

[Cirrial]

As reported by Dexter Grifflez, and I'm posting it here:

I self-surgery'd myself to insert a medkit into my chest. Went perfectly fine until I went to suture myself shut without securing the medkit. Instead, the suture was overridden by the medkit which teleported out of my chest and into my hand. The medkit now teleports to my hand when I pat myself on the chest. Using a scalpel on grab intent to extract

Can't replicate it myself, can't figure out where in the code it's going wrong. It's not a dupe bug, the item just appears to exist in two places at once (and cause strangeness as whenever this sort of thing happens). I've added a temporary fix that checks for the item being in the chest when things need to happen to it, but the root cause eludes me. This is a call to the other coders to PLEASE HELP
