Items disappeared on the shelf

[Llama]

So, I have two things going on. The first is one of my handlers apparently stealing batteries. I don't know what he needs 160 D-Batteries for, but this has been discussed in the forums so whatever. The other problem I'm having is stuff disappearing right off the shelf. One of my chemists took some finished product and put it on a shelf next to the brick packer like they're supposed to, but then after a while it just... disappears. I was watching it to see if it was being lost in transition or something, but nope. Somewhere between me seeing my chemist put the product on the shelf and me watching for the handler that puts the product in the brick maker (no one showed up btw), my meth disappeared. If it's them ♥♥♥♥♥♥' meth-gnomes again, I'm going to be pissed. I just got rid of them.
