First of all, Load order... Should it always be at the very BOTTOM of my load order so that it overrides all other mods (I heard putting mods at the very BOTTOM of the load order causes them to basically dominate over all other mods and have supremacy)... I don't understand load order in general. Crash course requested as well.

Now... There is an issue in my game, I believe caused by the patch, and in the comments section at Bethesda.net, there are the same complaints in the thread under the Unofficial Skyrim Xbox One SE Patch...

Rectangular/square Orange/Red Glowing shapes on the floor/ground. The only one I have encountered so far is in Riverwood right next to where Hod processes lumber on the floor of the mill, right up the ramp, next to the lumber pile right on the floor.

A Large, rectangular, BRIGHT Orange/Red spot?!?!

How would I go about reporting this as a request to "Athgramoor" I believe is the author's name??

I thank you all in advance. I realize I have packed allot of questions into this one topic. Please help me.

I was under the impression that mods are loaded from the top-down, not vice versa. So to get the unofficial patch to load first, put it to the top of your load order. I think this is true, because I have a mod that requires being last in the load order to work, and when it isn't at the bottom of the list it doesn't work.

I also have the same issue as you regarding orange squares, except mine appear in the doorways of castle Volkihar, big door-shaped orange shapes.

I believe the author of the mod is a member of the forums here. There might even be a thread for it existing already.

Arthmoor is likely already aware of the bug. For posting about bugs and such it is likely best to post here http://afkmods.iguanadons.net/index.php?/forum/351-unofficial-skyrim-special-edition-patches/

Unofficial Patches should be near the top of the load order just below the Official DLC's and plugins.

Indeed. ESP/ESM based load orders are usually prioritised from the top down, hence Skyrim and all its DLC being at the top.

There is a member called Arthmoor here; I assume he's the "real" one.
