Hi
@odinrizhanin,
I hope you're doing well. This is not a bug, but I can understand the frustration. This is something that is being addressed. It's a limitation of EAGLE's polygon implementation, our devs are aware of it and long term there are plans to address it. For now be assured that it won't create any issues on the board.
Let me know if there's anything else I can do for you.
Best Regards,

Jorge Garcia
