Hey again,
The previous reply was a bit rushed. Let me try to give you a better answer.
First off, well played to get that far and have that many crew, especially this early on in the beta.
Waste is a resource, it can be moved to another storage by using the storage datapad app. And it can be used in things like reactors.
The dual storage bays making things grind to a halt is a bit hard to diagnose from this. It could be a bug and it could be just the circumstances of your station. In order for us to investigate properly we will need your logs and potentially your save game from this session.
Unassigned check-in tasks are a bug that we have thought we had gotten rid of. If your version (as it will say in the lower right corner) is 0.4.0 or higher then we would very much like to get our hands on the game logs and possibly the save game from this session.
Hope this helps,
Daniel
