Moving guns on a ship

[FactionHeir]

I found this rather strange thing recently and have not noticed it prior to 1.3 though I may be wrong:

I had a galleon that came out of several victorious autoresolves and fought a battle manually this time around. I notice at the start that onlz the left side has any guns working, right side all gone.

So I sail with my left side towards them and fire away. After a while, I need to turn and happen to face them with my right side. Out of nowhere, my right side bombards them heavily. I check and notice all my guns are now on the right side! Left side all gone!

So eventually they get over to my left again, this time with me hovering my mouse over my guns. Lo and behold, my guns are slowly moving from right to left.

While that's obviously a nice feature, I do wonder whether this is supposed to happen. Afterall, your guns are destroyed on one side and its probably not exactly easy nor quick to move some 20 cannons from one side of the board to another within minutes and have them ready to fire.

After the battle and entering the next, the guns remained on the left (even though I ended previous battle with guns on right in the end) and during the following battles, the guns would still be shifting about.
