Describe the Bug

Sending DisputWindowPost succeeded but no reward, the last DisputWindowPust succeeded with a reward, I'm wondering if the reward was canceled or if there was a problem with the lotus

The reward comes from the Miner Actor's balance, and this Miner had no balance. It looks like they:

1. Submitted a bad window post.
2. Terminated the sectors in that window post (burning some FIL, but also unlocking their pledge).
3. Withdrew their pledge.

This is definitely an... interesting edge case. But there isn't really a way to "pay out" in this case because there simply isn't any FIL.

Thank you for your reply.

Closing in favor of #11715 (with a description of how this should be fixed).
