Drills don't Drill properly

So I have been making miners since SE1 for a looong time. I am not comparing SE1 to SE2 as I know they are different games with different engines, however, here are my findings:

1. Too many Drills causes ships to just not work

2. Large Drills are WAY more buggy than the small ones

3. Certain Drill layouts seem to not work for unknown reasons

So far, the largest drill ship I have been successful in building is my Star Borer V4.0 (it is on the workshop) and it works perfectly.

Now here is the issue, I have been working on making the V5.0, using the EXACT same Drill layout, just adding more rows - it completely fails and gets stuck on an "invisible wall" after barely a few meters in... That's the only way I can describe it, visually there is no reason for it to be stuck, there is even room in front of it - it's not even touching the asteroid but is unable to go forward. Additionally, attempting to just force through by going forward at very low speed (2-3 mps) results in blocks randomly breaking. These blocks are not even close to the drill area (though they are near the base of the Drills themselves).

PS: I have attached the save where I was designing Star Borer V5.0. The one with the invisible wall bug (though it doesn't work on other saves too for this ship which "should" 100% work for sure.
