Basically, I start off a session in Cyrodiil able to repair and set down siege weapons. As I continue playing, I can't repair, then I can't set down siege weapons.
They said something about poisons proccing preventing repairs in the patch notes, but I haven't been into Cyrodiil this morning to check if it fixed the problem I've been having with being unable to drop siege weapons.
I've had that too. Got a duplicate meat pack in my inventory.
Couldn't delete it, and trough that i couldn't use anything siege related trough my quick slot.
After leaving cyrodiil i was able to delete it.
Happened just once for me now
