Tubes are hard to get the hang of at the moment. Here's a quick guide:
- Tube-Ports will take resources from any adjacent plots and store them for usage in construction/depositing.
- Tube-Pumps will take from the two plots that aren't selected, and push them into the selected plot.
You have to be careful you don't have 2 tubes trying to take from each other, they will pass resources back and forth!
