0.4.20 Patch Notes:
* Fixed an issue where modules could result in weird behavior when replaced with other modules directly.
* Fixed an issue where with enough random clicking you were able to mess up module stacks where they would eventually end up stacking as 1 instead of 5.
* Fixed an exception caused by a null localization string.
* Fixed an exception that happened when trying to deselect a no longer existing entity.
* Click, hold and dragging items is now supported. Useful for players who are used to holding mouse button down while dragging items from inventory to quickbar for example.
* Fixed an issue where some movers would become homeless and wouldn't look for a new home, appearing to be stuck underground
* Hovering over a worker now highlights the workstation they're assigned to, if any.
* Fixed Pipette tool not working on walls.
