[2020] Non stop crashing at my main base

Hello @3DG3, welcome to the community!

Would you be able to share some screenshots of your base and an estimate on the amount of building pieces, decorative placeables and light sources, so we have a feeling for its scope?

Additionally, could you try to perform a clean reinstall of the game and to rebuild the PS4 database, to ensure that the issue is not related to the current installation?
