Mecenery crossbow skill can't shoot

Mecenery crossbow skill can't shoot
if change weapon can hits monster except crossbow

Did you reload your crossbow? Do you have the skill on left click?

If so try holding Shift then pressing the desired skill.

Let me know the skill too. Made a merc here and its firing all my skills but im just a lowbie.

Skill is on slot1 and right-click. full ammo. also try hold shift but still can't shoot.

Do you mean the "Crossbow Shot" skill or one of the "Load" skills (e.g. "Fragmentation Rounds" or "Permafrost Bolts")?
For shooting you need the Crossbow Shot in one skill slot, and with the "Load" skills (or the default "Basic Bolts") in other skill slots you select the current bolts to shoot with.

In Some of the abilities of my mercenary characters disappeared from the skill bar I've helped another user with this issue.

EVERY SKILL (Crossbow Shot AND Fragmentation Rounds AND Permafrost Bolts) THAT USE CROSSBOW CAN'T SHOOT ALSO.

I have also encountered this and know whats happening but am unable to fix it.

When i have 2 Xbows equipped with different skills on different sets, changing ammo or weapon works properly, but it tries to load the ammo into the wrong xbow skill. i have 2 xbow shot skills, but only 1 will load ammo, so it automatically changes the xbow back to fire or wont fire at all. i have tested out manually changing xbow shot and it will fire the ammo on the other set but will no longer fire the ammo from the first set.

End up with a weird visual of 2 skills active on the hotbar, but either 1 or none will fire.

Since im unable to set xbow shot 1 as set 1 and xbow shot 2 as set 2, i think it gets stuck and loads everything into shot 1.
