I have been using it to buy runes from Aubury, so far with moderate babysitting. F2P only so far.
The main reason for the babysitting is fighting with the auto-logout from world hopping. So far I've set the sleep to at least 7 - 8 seconds and it'll seemingly run for an hour before I get logged again. Is there a recommended time for this?
Otherwise, I've encountered the problem where the script will be in "world hop" status, but only hovers over the world and won't click it (F2P). Pausing and Playing again seems to fix the problem for a while.
