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, therefore

it would be interesting to run batctl ll tt; batctl l all the time on the node
that usually experiences the "problem". The log should be not so big, unless the
bug happens.
