Trigger:
- Have the game running, not in tower testing
- Lock Windows
- Wait a few minutes - 5 to 10
- Log back into Windows and open the game
Effect:
If you are dissolving materials in the factory, the dissolver will stop working - it looked like items were also still being consumed, just producing nothing
Side effect of the above - the fabrication rate significantly reduces as the stored-up amount of mass will quickly deplete and you will have no saved mass
Additional effect:
Go to the power plant and you will see that the stored energy you had before has been reset to 0
(This may take longer to have happen - it happens to me every time I leave the PC for a few hours)
In both cases I do not have workers doing anything related to those tasks (I do not have a worker starting boosts and I do not have one on the dissolver). As it is I currently only have orders on 4 workers, the rest are idle.
