Re: Holiday goals box not showing up

The amount of mods may not be a problem, however, within that 4 thousand there may be a mod or several that are causing you problems.

Please remove the mods folder and test the game to see if the issue still occurs (don't save on your current save which contains mods/cc).

If the game works without the mods then you will need to find which mods are causing the issue and make sure they are updated to the latest patch/removed.

Here's a technique you can use for finding troublesome mods: https://twinfinite.net/2020/02/sims-4-broken-mods-how-fix/
