Sims 4 is not a finished game. The code is always changing with every new update. For that reason, some people may choose not to use mods at all. If, like myself, you do choose to use mods know that every time there is an update for the game, your mods may also need updates.
In the General Mods Discussion area of this forum there is always a thread open with information on broken and updated mods. Many modders, such as Deaderpool, also have Discord channels with information about mod updates. For me, the mod updating process is sometimes a hassle, but I enjoy my mods enough to make the commitment to frequent updates. I am very thankful to those in our community who give so much of their time to keep us informed about updates; @luthienrising does an amazing job with this on the forum!
Some people may find mods more of a hassle than they are worth, especially those who don't play frequently. At the moment I am waiting to play with the new update until all of my must have mods are updated, while those without mods are already playing. I enjoy modding my game almost as much as I enjoy playing it, so it is not a huge sacrifice for me. (I could also remove my mods and play on a new save if I really wanted to just explore the update.)
Another thing to keep in mind about mods is that they don't always play nicely together. I recommend adding just one at a time and seeing how it affects your in-game play before adding another. I had a conflict between Zerbu's Go to School mod and LilMsSam's mod that disallowed auto grab after food preparation. Not something I expected, but the cafeteria chef would not prepare enough food with the auto grab installed. Not game crashing, but it was annoying. If you only have five mods, I would remove them all and play in a temporary save to see if your problem is solved. If it is, then you can slowly add the mods back in until you know which mod or which combination of mods is causing the problem.
