First, some context... I use carronades on my Britannian ship.

Last night, I was doing some plunderbeacons with Melek and Xtal. All of my carronades were in "Pristine" condition. We got the first plunderbeacon down, and I repaired the cannon. On the second plunderbeacon, however, even starting with a pristine cannon, it disappeared within up to 6 shots. Cannons on ships are notoriously buggy, sometimes floating out over the water or having wonky placement on the boat, so I thought maybe it had jumped out somewhere I couldn't see it while in transit. After several frustrating minutes of searching and trying to figure out what happened, we concluded that it must have been destroyed.
In my experience, a cannon could fire all 14 times at a plunderbeacon, and by the time it was down would be "Moderately Damaged" to "Heavily Damaged" at the WORST. We got to the point last night where I was repairing the cannon we were using after almost every shot, just to be safe. I lost 3 cannons last night before we started repairing obsessively. I'm really not sure if cannon durability has changed? Maybe it's random now? Can you lose a cannon at any time, regardless of repair state?
We also had another minor issue where the characters on the boat were all set to "CREW" access, but not everyone could SEE the contents of the cannon to be able to fire it. Some saw 3/3 items with visible powder charges, fuse cords, and cannonballs present and accounted for, others saw nothing, with 0/3 items and a seemingly empty cannon. This happened with the same cannon that disappeared after a few shots.
It seems like there's at least one bug here involving cannons, but I don't know enough to put my finger on exactly what. Looking for input!
