While trying to assemble the rocket, picking up one of the boosters turned invisible and now I am stuck. Escape is not bringing up any menu. Most other menu shortcuts do not work, like inventory, knowledge, and the like. Only this option worked, the movement keys move the character, but the LMB and RMB do not react. E key does not react. The only option I have at this point is to force kill the game and pull up the last save.
