Khal, sorry for my incomplete response i was in a bit of a rush,
first off.
Your Astral script is close to perfect, it has a few banking issues every now and then, for instance it opens and closes the bank twice or maybe three times in succession? not entirely sure why, it does this randomly every 15 trips or so. this is inbetween the step of filling pouches so it'll fill the pouches open bank then immediately close without drawing anymore pure essence. Also what i meant by the pathing, is it will sometimes wall past the astral altar all the way to the edge of the land and then double back towards the altar. maybe once every 10 trips, this is the most notable "bot-like" issue it has. I have to say the Astral script is the most consistent out of the 3 methods i tried, averaging ~17k xp/hr
next
Your Lava running script, not entirely sure what is the issue, but when it walks into the fire altar to craft the runes it'll run around the room very bot like, I am willing to record a video and upload to youtube and PM you the private link if you would like in order to better troubleshoot the problem. I only get around ~12k at max running lava runes because of all of the bugs.
lastly
Your Nature running script, as others has stated it has issues finding obstacles to navigate within the abyss. it will stand in the center of the abyss where you land when teleporting sometimes (not all the time it seems to be random), and sit there until I manually navigate it to the obstacle then it'll continue the script from there.
EDIT: Also in your Astral script whenever you start it while wielding a staff of earth it'll still open up bank withdraw one, and then derp like "oh you already have one on" then bank the one it withdrawn, also quite bot like but only once per script start so not so bad.
Also idk if there is a check if you have random items in your inventory but for some reason i keep ending up with random items in my inventory from my bank while runecrafting Astrals
