I've noticed that when recycling building or workshop pieces, that you never receive all of the parts back that you put into things. It would be much nicer if you got every item you put into build something back, particularly as finding a perfect base location often relies heavily on your advancement in the game as better materials become available. It's frustrating to have to gather building materials again for the same things. Just a suggestion
For building items, for bases etc, would be nice if these too pulled from existing chests, provided you're within range of them.
The Aphid Slippers don't seem to really increase running speed. If it's intended that people will forego proper armour for speed, maybe increase the speed on this.
