This is an issue that affects mostly SR3->BM1 builds.
-> What happens?
When casting Double Gun Stance skill from Bullet Marker while riding a companion near many monsters sometimes you’ll fail to enter double gun stance but also be unable to recast it.
After the bug happens the skill gets stuck in disabled/grayed state and you’re only able to recast it after riding a companion again.
-> What’s expected to happen:
If Double Gun Stance cast is cancelled you should always still be able to recast it. Either for entering or leaving double gun stance. The skill should never be disabled/grayed out.
-> Possible causes:
A) Client-side bug that doesn’t re-enable stance skills if the cast is interrupted while also dismounting a companion.
B) Lag-related issue where inconsistencies happens with riding state, stance and cast interruption, because a race condition where functions gets called out of the expected order.
-> How to reproduce:
-
Enter a Challenge Mode portal on Sausys 9 map as a Schwarzer Reiter 3 -> Bullet Marker 1 character. It is easier to reproduce if you bring a 5-players party to attack monsters to cause lag and simulate a real Challenge Mode instance.
-
Once there’s a lot of monsters near you, while mounted cast the Dual Gun Stance skill. You should automatically dismount the companion and switch into dual gun stance (buff/stance) normally.
-
Mount your companion again and repeat 2 while monsters keep attacking you.
Intermittently, you will notice that after casting Dual Gun Stance skill you will dismount the companion but won’t enter dual gun stance.
You will be unable to cast Dual Gun Stance skill because the skill is disabled and won’t be able to cast Bullet Marker skills that requires dual gun stance.
The only current fix is to ride a companion again and recast the skill.
The only current workaround is to dismount a companion and wait for its animation to finish then cast Double Gun Stance, instead of relying on the feature that dismounts the character after casting a skill incompatible with riding state.
