When I use the desk, the elements sometimes desapear. One time, I was reaparing a print motherbord (I dont know if we call it like that in english, I speak freanch usually) and I clik on the right button of my mouse and the chip desapear. An other time, I improve my ''disqueuse'' and while the desk was upgrading it, I went to do something else and when I came back, my ''disqueuse'' was not there anymore, not in my ''inventaire'' and no where else. When things like that happen, I save de game and restart and everything go well after, but its always not fun, a bit scary hahaha.
