I discoved a bug and managed to easily replicate him multiple times. This bug prevents you to swap weapons (see disabled weapon change button at my screen) even when you do have second weapon set.
So, to the mechanics of this bug:
1) be in combat
2) swap weapons
3) a cutsceen has to occur during refresh time on swap (normlly 10 sec, my warrior 5)
4) that cutsceen has to end during refresh time on swap (basicially, you skip it)
Ideal way to test this bug is at CoF right after gate, but I am pretty sure I encounted this bug even in fractals.
The ways to make your second set work again are:
a) Go through a loading screen .
b) Get out of combat, remove your second weapon set and put it on again. Problem is, you usually won’t notice till fight (after cutsceen often boss fight) begins.
