everythign that doesnt have a ownable block (for example cockpit, refinery, gyroscope) on its own grid as neutral, jep even if it is a subgrid (wheels count as subgrids) that is attached to a grid that has ownable blocks but none on the subgrid, and a ssuch the standard setting of the bars of the janitor funtion beeing allowed to gridn away neutral stuff grind them away.

from experience this sometimes also happens on relative large grids (over 5k blocks) to some armor blocks cause keens ownership system designates them as neutral once they have a certain distance to a ownable block.

its happening since keens slight ownership rework that came together with the survival update.

as far as my informations are this happens sicne keens slight overhaul to the ownership system aroudn the survival update.

I have the same problem.
I can´t find anything online about this issue, no one seems bothered by it.

The comment above by Abisius (although abhorrently & incomprehensibly written), seems to be true.

Random wheels and random blocks classified "without owner" on big large grids.
I added a group of all wheels "add wheel" action on my rovers, that's how often it happens.
And I can't count the holes it left in my base, disconnected conveyor lines, armor blocks missing everywhere ...

Please let me know if anyone finds a solution. I'm desperate.

yeah my translations are more than just a bit wacky.

i for my part started to look around for alternatives to bars cause it doesnt look like its getting an update anywhere in the visible future for the probs it started to accumolate over time since the last update.

there are already a few alternate versions of bars in the workshop that have slightly altered functions and most dont seem to have this prob.

at some point i will probably land on one of them or on the nanite control facility (which has its own fair share of probs) or ai enable (doenst work with nanites and work differently but is basically also a helper), though i still hope we get an update for the original bars that fixes it.
