So, a while back I had 20 Bridge & Milegate Repair Kits. I put them into storage in a chest, along with a bunch of siege weapons I wasn't using.
Months later, I took everything out again because I've been doing more Alliance War in Cyrodiil during this event.
Now, during that time I have not in fact repaired a single bridge or milegate... But all my Bridge & Milegate Repair Kits have disappeared. They're not on any of my toons, they're not in my bank, they're not in any of my storage chests, nowhere.
However I seem to have suddenly gained 20 "Siege Repair Kits" out of nowhere. Now, I don't have much use for these because you almost never get to repair a siege weapon: either you're attacking a castle with zero or poor defence, in which case your siege engine never gets damaged, or you face heavy defence and have to retreat, in which case you usually get killed and your siege weapon burned. They're generally cheap enough not to need repair in any case, and I have too many anyway.
I looked at the UESP spoiler site and ALL mention of Bridge & Milegate Repair Kits seems to be missing - it is not listed as a thing that can be bought at Siege Merchants, or in the list of Repair Kits, where they only list the repair kits for siege weapons, keep walls and keep doors...
So I wondered if they'd been deleted from the game, and conflated with the Siege Repair Kits...
But there are still Bridge & Milegate Repair Kits available at the siege merchant?
Wondering what's going on...
