"You can't loot that item now" with playerbots

[dbq]

I been experiencing this issue in my small mangos one server.

When I play by myself, all lootings are fine.

But once I add a playerbot, the following lootings will consistently(logout, restart client won't help) fail with "You can't loot that item now":

• All quest items from corpse or clicking on a quest object
• All gathering items(herbalism/skin etc)
• All disenchanted items
• All items require a right click on another item to "open" and loot, e.g. pearls and meat from a shell.
• Chest loot are sometimes fine

Happy to look into code if anyone could share some pointers.

Thanks

also, both my character and the playerbots are experiencing the looting issue.
