2nd attack bug: Fixed!
lvl 3 interrupt bug: Fixed!
lvl 3 infinite duration bug: I had it happen once randomly (the first time I launched after installing the new version). Isn't reproducible like it had been with the interrupt bug though. So fixed-ish?
And the ghost hit bug is also less consistent now, but still sometimes happens.
From my testing so far in the new build, the bug never triggers when the combo includes:
-a missed attack.
-a hit which breaks an enemy's guard.
-a hit which kills an enemy.
It also only triggers on an enemy who got a knockback effect from the attack that hit them, which usually comes from the final hit of the combo.
It won't trigger every time those conditions are met, and I don't know what, if any, other conditions might be relevant. When I knock an enemy back and they end up next to a second enemy, sometimes the ghost hit will stagger both of them, but that's not consistent either.
