Fee jumped ""channel ALL: lightning_closingd: Their fee jumped 14661 to 13410 when ours was 14035""

I got this error connecting to peer 039a8f88dca257f4f67a2c65bfcc6ab1d398488334d3b3a78d514c8e3f6638a903:

"channel ALL: lightning_closingd: Their fee jumped 14661 to 13410 when ours was 14035"

In the log:

"Their fee jumped 14661 to 13410 when ours was 14035" repeats in the log 5 times (presumably whenever I tried to reconnect). I think I might have found in the log where it went bad:

What's going on? How do I get more information about this for debugging? Is this supposed to happen?

What was remote end? They're supposed to get closer to our offer, not jump over it!

I'm confused by this sentence:

"Their fee jumped 14661 to 13410 when ours was 14035"

So the fee was -1251, jumped 14661 to 13410, when ours was 14035. If it was -1251, then it getting closer to our 14035 means it's getting better, right?

But, your interpretation isn't what the sentence says. Your interpretation would be written this way:

"Their fee jumped from 14661 to 13410 when ours was 14035."

Perhaps your misinterpretation is the correct one, and it helps me to understand it better.

You used the word "jump", which the error did too. I wonder if it was a translation error. "Their fee jumped from 14661 over ours at 14035 to 13410."
