Abandoned tray BUG in a box Box for circuits and pendrives:
IF you use an "abandoned tablet" in a box "box for circuits and pendrives" so it reads THEN THE tablet STAYS in the BOX. Unlike in your inventory where you lose it after you learn something NEW from it, if you have it in such a box and want to learn something new it stays because you read the tablet SO you can read it again afterwards.
This is a BIG BUG
Either you can ONLY READ it in your INVENTORY OR YOU HAVE TO REWRITE THE CODE SO THAT IT WILL ALSO BE REMOVED FROM A BOX "Box for Circuits and Pendrives" AFTER YOU HAVE USED/READ IT. It's easier to simply display the NOT usable option in a box that you want to read.
