PvP gamebreaking glitch for griefing using unbuilt blocks
Im reporting a very ancient bug where a griefer can use bunch of steel plates to do massive damage to bases both in space and on planet surface.
Griefer takes several steel plates, flies above the base beyond turret range and drops unbuilt artificial masses. They have full mass upon being placed, light blocks do nothing when dropped. They are not targetted by turrets with any settings and upon impact deal massive damage to the base. Griefer can also stand on the roof and place the artifical mass above his head, smashing through the ceiling and several floors.
In space, griefer accelerates with his jetpack to max speed and places the artifical mass block. Same result as on planets. I have a save file where tester has to just press a left mouse button, but I can't upload it into files here, so I recorded a gif instead.
This sort of attack requires no engineering whatsoever, just a few steel plates, and should not be possible.
Steps to reproduce:
1) Create an Easy Start Earth survival world
2) Take steel plates into your inventory
3) Fly directly above your (or any other) base
4) Place Artificial mass block directly below you
You might have to spend 20min unlocking it. That hasn't stopped any of the griefers I saw at test#3 though.
