Re: I can't change the color of clothes in the sims or build anything in build mode.

@VexDazxt  Try repairing the game in Origin: open your game library, right-click on the Sims 4 icon, and select Repair.  If that doesn't help, clear Origin's cache and repair again.

If that doesn't help either, please remove your mods long enough to test.  You can use a new save rather than your current one if you want, but your existing save should be fine as long as you don't save your progress with the mods missing.
