Exactly! If the neighbour has the needed information, the node can directly=
 get
answered without bothering the real destination ;)

Well, the log you posted is perfectly correct. You missed some OGMs, theref=
ore
the node is asking for an update that he missed.

it would be interesting to run batctl ll tt; batctl l all the time on the n=

s the
bug happens.
