i found a funny bug.
steps to reproduce:
1. build 1 "gas refinery"
2. build it on the ground
3. remove it
4. voila! You have an "advanced gas rafinery" in your backpack

Found it because i was tryin to find out how to do plastic, after i finished i want to scale it bigger, but couldnt find "advanced gas rafinery".... then i thought, build the normal one, needed to rearange it... and voila! Works everytime.
But its shit, becasue the advanced seems to be worser...? Double bug?
