Currently running .24c This started a few releases ago, around v0.23'ish . I keeping finding my bot standing in town with Inventory and Stash open and (originally) the #1 flask on the cursor. At first I fixed it by just not having a flask in the 1st slot but since .24c I come back to find it standing there with the flask from the #2 slot on the cursor.
I only set the bot to running when I go to bed at night and I stop it when I get up in the morning. Sometimes the bot is still farming when I get up in the morning and other times it is standing there with a flask on the cursor. Sometimes it does this after only 10 or so runs, sometimes it does it after 100 or so runs and sometimes it makes it all night without grabbing one of my flasks.
Haven't had a chance yet to see if I can start putting a flask in the #1 slot again and now just not have a flask in the #2 slot.
