I never have problems with expirienced jackals.
Nr 1 reason is, that I simply evade the encounters so easely.
I do that by simply going for the north or south exits and then
berserk kill the jackals standing next to me or i simply spell
blast them - it always works.
Secondly I will simply breach through and kill the jackalwere
before he summons more if I meet them in the caves.
These tactics always works, and therefore it simply cannot be
said, that the jackal effect is a bug.
