So instead of going for free through channel 722806x2422x0 the payment cost me 2000 sats and went this route: 643142x1807x0->649865x117x1->709726x1985x0
This is not at all how things should work… channel 722806x2422x0 is online and has plenty of funds. In fact sendtoroute through that channel works just fine.

With the default path-finding params, 40% of the score of a path depends on the age of the channels which puts new channels at a massive disadvantage.
path finding is default and I checked for channel ID and node ID, to be sure to not miss anything
and yeah, it was a rebalance attempt shortly after channel creation.
