Found a weird bug. It's concerning though, since the bot could have been going around with full inventory some time blacklisting every drop.
It looked like, the bot tried to force townrun but it was never launched. The first time I watched it, the bot was trying to get the item just in front of a arreat flamethrower, and I thought that maybe the flame hit could be interrupting townrun, but I just let it go for a little longer and it went to another position, tried to pick up another item, and just didn't get it nor launched townrun.
EDIT: I just updated Trinity, rixx profile and questools to last versions, It seems it is trinity related but you might know better. Db version was 302, not updated to Beta.
Log:
EDIT2: Another bug. Switched back to trinity 1.7.2.3 and had one bot create a game, and it just tried to recreate another game inside, with the related dreaded error window in D3.(Not crash, the error window inside d3) 2nd log coming! At that moment yar was opening several d3 and db instances, it could be of relevance to you.
