Zeek the garden center works fine for me and I have the patch and ep - but as the other simmer said the watering is random. Most of the time I have to click one of the sprinklers and then it comes on. The compost bin will still do compost but again not automatically. I put the 3 sunshines in there, then hit the _ Use compost button for it to work. So the automatic functions seem to have been unset. That is the only thing I have seen off with it.
Also I have not had any additional lag in any worlds by adding Grandpa's Grove. I have it as well as the version Amjoie made in 4 different worlds with no issues in any of the worlds. 2 are user made by Rflong as I am also testing those two worlds and the other two are Moonlight Falls and Dragon Valley - so far. Grims Manor works good every where also. The new Bistro with the chefs oven works good, as does all the Uni PC type stuff like bowling alleys, the barrister bakery bar. The Dance Venue, the Open Market, the Casino, the Arcade, Haunted Library, Fountain of Youth, Spellbook (actually all magical PC works well and has their animations), the new Movie Theater - are all Iitems I am playing without issues in the 4 worlds I mentioned.
I do have the Learning center, the baby pen and walker, LL, and the Tree of Prosperity not added to my game - this testing has been with a totally reset Sims 3 folder, with all the store content reinstalled - all new games, no previous saves, and reinstalled all my own studio stuff and sims. So no saved anything - all new - and I did not this time install those things. IP is unplayable. I did try all the ep worlds briefly to see if any lag with the farm added to each ep world and saw no unusual lag. Have not tried the store worlds but Dragon Valley yet. So I am not seeing any issue with it in a new game start in Riverview. I only played each world about 20 minutes using the EA made Prius family with the mom and dad and 2 kids.
Hope that helps in your search for answers.
