Re: Unable to start event after putting in mods (Sims 4)
@GlacierSnowGhost The issue with TOOL Mod is that it's current not compatible with the Events UI or any calendared event; I don't know if it stops holidays. This goes back to before this patch. It's not a new issue. But you do need to updat TOOL or remove it completely; only the updated version is compatible with the updated game at all.
You can still use TOOL. Just take it out during gameplay.
I found out about the issue from the creator's discord server and its support people.
