Did this occur today? it's wednesday (update day) and there could be some breakages.
rune pouch support was planned but realistically there's no reason to do it that way over just withdrawing the runes as needed
it will work regardless if its on or off, but turning it off will make the bot change protection prayers at the start of the animation instead of 2 ticks after which is when the damage is calculated.
no risk, the bot uses a direct input to click on the bank to prevent any misclicks.
if you're concerned, get the hard ardy diary done to use the seers bank on a non-pvp world.
no plans for phials support atm, no clue how good it is
