Unfortunatley this didnt work for me, was at a few items below max cap, still same looting bug. Tried to make lots of room in bag after, still keeps on looting same pokestop.
It actually left the pokestop 1 time to catch a ? but then returned back to the pokestop and kept looting it.
Making it grind the same pokestop for a couple of hours now to eliminate the soft ban theory.
Will post back later tonight.
Have tested running the bot for a longer time now.
It walks up to a pokestop and loots it. After it has looted the first time, it tries to loot it over and over again. it keeps doing this for 20-35 minutes then it moves to nearest other pokestop and does the same procedure again.
I have also tested to stop the bot, log in to my phone and played manually to ensure there is no soft ban.
from my perspective it looks like the bot thinks it has a softban where in reality it does not.
