When path-finding considers a candidate hop, this adds the outbound fee of the "from" node and the inbound fee of the "to" node. Because those nodes don't necessarily coordinate fees, it may happen more often that the fee goes negative. Rounding up to zero is still a quick fix and better than ignoring inbound fees completely. -------------- next part -------------- An HTML attachment was scrubbed...
