So, I tried repairing the game, but the issue remains. I did some more testing and it happens on every lot in every world.
Like I said earlier, this is just so weird. And since it happens in all worlds, it's got to be something unique to your game or computer.
I did think of one other thing. I use a wireless mouse and keyboard which have batteries. My game will go for months with no problem, and then, all of a sudden, my mouse will become really erratic in TS4. Jumps all over the place. Can't click on things, etc. It only happens in TS4 too. It does not happen in any other game I play or app I use. Even though the little light on my mouse shows green meaning the batteries are still good, if I change the batteries, then everything goes back to normal until the next time they get low. The same thing happens with my keyboard except when those batteries get low, it just stops altogether.
So, if you are using a wireless mouse, then try changing the batteries. Put in some new ones. Or, if you have a wired mouse, try that one. That will tell you if it is the game or a hardware issue like low batteries. I know you said you tried another mouse, but if that one is wireless too, it could have low batteries too if it's been sitting around for a long time or if you moved the batteries between the two mice it could have just transferred the problem to the other mouse. And when you change the batteries, take a look to see if the battery contact points are clean. Clean them if the metal contacts are not shiny or look like something is on them.
Hope this helps.
I use a wired mouse and the second one was wired as well😅 So it can't be a battery issue. I also checked a few times whether it couls be like a hair or something on the mouse sensor, but it's not. And the issue is also only when building walls, never for example during furnishing, putting on wallpaper or during gameplay, literally only during building walls or fences.
This issue is still ongoing, but how bad it is seems to vary. This far the Spice District lots by the harbour seems to be the worst. Havr to build max 2 wall pieces at a time or it throws the walls off diagonally in all random directions. It really makes building almost impossible. Anything else I could try as a fix?
