Thanks for your replies! Yes, I guess I looked at civ screen, and indeed it doesn`t shows hostility, because today I got a goblin Siege (although quite small one, perhaps oddities of having a pocket size world)
Elves won't attack you at all unless you break treecutting promises, and that won't happen unless you fix their diplomacy via DFHack.
Hey, I fixed them with dfhack, It reported, that fixed 1 of 1 diplomat, but 2 caravans since then, and no diplomat

( what do? Dfhack now says that he fixes 0 of 1 diplomats, implying it's already fixed.
