The release was tested right after the update and the looting hadn't changed.
I just re-downloaded and tested a clean copy with no changes, and it's still working.
Make sure your filters are correct if it's not working at all.
The current looting logic does have some drawbacks in certain cases, that you might be noticing. Specifically:
* Loot that is close by, but not literally under you when there are mobs on the screen is not picked up right away.
* If there is loot to pickup, but the area transition to take to the next area is in range, the loot will be skipped.
* If the bot chains combat targets across the map, it has to go back to pickup loot after it's done.
Most of those issues will be solved in the next exploration update when it's finished. However, there's always going to be cases where combat logic tells the bot to keep doing combat, so the bot can't do looting as a result.
