Guild Wars 2

I have this monthly part stuck on 5/15
done tixx for four times already but the counter is stuck on 5/15
what am i doing wrong?

You can also go out into the open world(i farmed Frostgorge Sound) and the candy icons on your map are location of presents and sometimes toys will spawn for you to kill.

Edit: but no I have not gotten stuck at kills but try killing the open world toys see if that helps

ok, solved. sorry for the confusion.
you have to kill the toy centaurs during the turrets phase.

There is aphase where you got to destroy broken turrets. If your group does NOT destroy broken turrets, but instead just kills the toy centaurs, they respawn over and over again.

You can get to 100/100 for the monthly in one single dungeon: as long as you do not destroy 18 turrets, they’ll keep comming.
