I will have to double-check if F12 functionality needs updating (unless you are using using task scheduler?), in any case I will give it a look
Prayer flicking - I would only say it's dangerous if the npc is dangerous, for bans it's fine because it uses randomized timers under the nearest (rounded) tick rate, but not for long periods of time as it can be non-humanlike to prayer flick for hours. I would go with normal prayer and not pray flicking personally
TzHaar are generally supported but no special functionality for them, so no luring behind the rock and safespotting them just yet, I will see what I can do in the future ^^
Looting - will add an option to make it slower, sure Will see what I can do If you are worried about bans, you shouldn't worry too much about this, the bigger worry is the npc fighting location, I've seen some bans over at the basic levels (chickens, monks, goblins) but maybe only 1-2 reported bans doing slayer? (for months) which is pretty epic actually And they reportedly botted for more than 20 hours at a time so it makes sense.
