you can quick pray in osrs, yes, however quick prayer isn't even necessary.
My need is to enter nmz, click my protect from melee prayer with a full inv of prayer potions, and then leave my computer for an hour while the bot just sits there and gets attacked and clicks a prayer potion after it falls under 25 prayer left. So I don't think the bug has anything to do with quick prayer. Any way you could fix that, I would certainly donate to you in game!
