I've noticed some odd behaviours and I'm not sure if it's a bug or not.
- Polisher completely ignores glass
- Even after polishing, using a sponge on the panel will use up durability
- You can go over the same panel multiple times and it will play the audio cue as if it's polishing again
- For the cost, it would expect it to tackle rust as well, but I understand if that's an intentional decision.
