Ship drills fail to drill and collect surface rocks
Just like it sounds I was able to get some video evidence for this pesky bug. Essentially I discovered a specific chain of events that can cause the ship tool drills to no longer drill and collect material from surface rocks. Video evidence linked below.
1: have a flying miner and a ground miner such as a rover present equipped with drills.
2: take a small hit of material from the surface rock using the flying miner
3: take a small hit of material from the ground using the flying miner
4: switch to the ground mine rover and take a hit of material from the surface rock. best if drill head touches the ground first as the rover should be unable to collect anything other than trace material.
5: go back to the flying miner and remove the drills currently there.
6: connect a new drill to the flying miner via a subgrid. subgrid drill should be unable to collect anything from the rock at all. small trace materials might possibly be picked up.
7: switch to the ground miner and remove the onboard drill
8: replace the drill with a subgrid drill and attempt to mine.
9: from here on you should be unable to collect anything other than trace materials even if you replace the subgrid drills with actual grid drills.
Actual results: ship drills lose the ability to drill surface rocks on modded or vanilla servers
Expected results: ship drills should be able to drill surface rocks.
Notes: there is a small bit of randomness to this process. In some instances you might pick up small trace amounts of material, in other instances you will get nothing. trace material never amounts to more than a few hundred kilos. Large swaths of material can be broken up and the drills pick up far less material than they should have. Trace material is picked up randomly and behaves as though the drill head is farther away from the material than is indicated visually. I believe this could be a combination of collision models and possible code with the drills themselves though I am not sure.
