Rubia's trashteroids appear to be using a hidden shield module which is dropped when the trashteroid is destroyed.
(Interestingly, it seems to only drop if shot, not if it collides with something.)

I fixed it locally by adding "*-trashteroid" to the exclude list which covers all the different trashteroid sizes.

I would strongly suggest adding "*-trashteroid" to the default exclude list as the shields are unusable (they can't be added to any equipment grids) and you can't use recyclers on Rubia (and this mod prevents destroying items in containers) so there is no way to get rid of them without shipping them into space.

Thank you for your time.

*-trashteroid doesn't seem to have worked, I'm still seeing the debug shields.

I did test with just rubia and remains mod and confirmed it's these 2.

I dug through the file data for Rubia and found the fix, exclude grid: "trashsteroid-grid".

I actually confirmed it worked this time.
