My expectation is “almost everything” will be broken mostly in mods department, but some CC as well:
- CC walls/floors since these now have some additional parameters;
- CC windows/doors due to new placement mechanics;
- Plumbing & electronics CC since new upgrades to make them functional off the grid will be added;
- Items which electricity/water consumption should be counted for bills purpose, probably won't be broken but won't be calculated properly I guess;
- CC food. It wasn’t mentioned widely but I’m pretty sure I’ve spotted new option on the meal in sim inventory - add to favorite. Meaning cc meals will probably need an update for this and also for cc management feature;
- CC plants and BrazenLotus Plants Overhaul due to new planters and ties to lot traits. Also for cc management feature (harvestables);
- Probably all crafting cc, since craftables will have to be updated for new inventory management system;
- Not quite CC but maps overrides since older maps received a facelift + pollution seemingly will be shown on maps.
Anyways currently I've removed everything but CAS defaults from my game. Which is always a good tactics during big patches.
