I have noticed on our server that if you have spare space in your inventory you are able to keep your materials for item you built by putting another building material into inventory while in the middle of building. This can be done with building that take longer that 10sec to build.
Steps to keep the materials
select object to build that doesn't take all 12 slots
Have extra tank trap, material that takes only one slot in your backpack
Building starts press 'g' to open inventory
Quickly open backpack before 10sec build stage starts and transfer from your backpack to inventory.
and wait for building process to finish.
Will get something on lines of "You don't have exact building materials" or something like that and you get to keep materials in your inventory.
I don't know if this is meant to happen, so it is easy to obtain materials and start build base or at least walls for it.
I will do quick video within next 24hrs to demonstrate.
EDIT:
Also noticed that the built object do not save into database, so no wasted materials, no buildings after restarts. Sort of like a temporary base.
