Issue with engineering borgs and the grinder
Created by: Gringonius
Description of issue
Engineering cyborgs can add whatever grindable materials they hold to a grinder, several times to the point that they can add the grinder to the brim with just 1 sheet of material. After that, as soon as the grind is used, the the icons of the material the borg had inserted will vanish and it will become impossible for the player to use them again, the only thing the player can do is synth them past the 50-sheet limit so it drops to the floor for humans. But they cannot ever build with said material again. Closing the client and reconnecting does not fix this. This does not happen to MoMMIs when they try to insert their own internal stacks because the game prohibits it.
Difference between expected and actual behavior
For the materials not to vanish from your UI and for the grinder to not take pretty much the same stack several times.
Steps to reproduce
Be a borg, synth and add metal/plasma/silver/gold/uranium to a grinder and activate it.
