I played with the gaza deeds a little bit with a water trough. Haven't done a whole lot with those and didn't have much in the way of deedable multi-tile objects that I knew SHOULD be able to be broken by using the gaza deeds. I was able to raise gaza deeds next to the stair railing in a keep and place a water trough on them; lower one deed and then half the trough to break it, and then axe away half of the trough. (See 3rd and 4th screen shots.)
I forgot to mention that when I was playing with the trough deed and gazas, in addition to being able to get the trough to show a split and lower or raise the halves independently of each other, I was able to raise the two pieces back to the same level and redeed it. As noted earlier, I did finally just split it and axed away one half of it. Of course at that point, the remaining half wouldn't redeed and poofed for good when I used an axe on it. So I THINK this aspect of using gazas to split stuff is working as it used to.
What seems very off, though, is placing stuff near tapestries.
I hadn't thought about the new banners yet and trying to place stuff near those, so I guess I'll play with them a little bit. They don't go into deed form once you get them though, so they probably play by different rules than the tapestries.
