Sims 4 Buggy since terrain update?!

I am pissed to the point of just not even bothering with flipping EA and Sims anymore and I have been playing since classic...

My paint tools work fine but the flatten, smooth, rise, lower and so on do NOT work no matter what I do. I do have mods...skin, eyes, hair, makeup, accessories and I think a few clothing. Wouldn't have to use mods if EA bothered to make the skin, hair and eyes not look so bloody fake but whatever. This terrain issue didn't come out for me until Strangerville and I had been working on the trailer lot with a story line behind it, however when I went to add a basement to that lot it bumped the top land up in the same size the basement was. This would then remove anything on top of the land (plants, furniture) and no way to flipping flatten it out.

So now I am kissing that house that I have spent hours on goodbye and the story because the terrain tools wont work. Also I don't know if its just me but the size of the square/circle of the tool size never goes small enough to do anything. Like they stay rather large so I can't really target in onto the area I am trying to work with. Terrain tools are not a new concept to EA in Sims so why they are messing it up this bad is beyond me but I am losing my passion for Sims fast...
