An armload of bugs

[Clarks]

2) Once an arm is reattached to you, a phantom arm will appear in your hand slot. Having the arm there won't break use of your hand.
You can take the extra arm in the other hand and throw it away. Or even implant that arm on somebody else.
I haven't reattached many legs, and I'm not sure whether those are bugged as well.

Just found out that legs do this too.
