Yes, just like Redabyss said, for now, you have to wait for the next update to fix issues that could cause it. You can clean your save in case of problems like that though.
There is a chance that after updating or by bugs you will have issues with stuck variables. The best way to deal with them is to clean your save.
You can clean your save in two steps, but start with doing just the first step and see if that helped.
1. WickedWhims saves most extra data in external files that are not embedded withing game saves. Go to you 'saves' folder (Documents\Electronic Arts\The Sims 4\saves) and delete the folder called 'WickedWoohooMod'. You will lose all your settings related to WickedWhims and some extra data, but that should help with possibly stuck variables preventing using the mod.
2. Some extra data is saved using in-game systems. You can clean that by removing WickedWhims from your 'Mods' folder (Documents\Electronic Arts\The Sims 4\Mods), turning the game on and saving it. Saving the game without mods installed will remove any extra data that is not needed anymore. You will lose all of your WickedWhims content like skills, buffs and traits, but that should help with possibly stuck variables preventing using the mod.
