Pretty sad that it's been 2 1/2 years since the OP and yet this problem persists! My roommate has items in her city that I need to use in order to complete social tasks but when I visit her city they never show up in the houses. To make matters worse, Sims Freeplay instantly crashes and closes about 90% of the time when I visit and tap to enter one of her houses! How am I supposed to complete social tasks and earn SP if I can't visit a neighbor and use their items??!?
I also find it ridiculous that they've never bothered to add additional ways for Android users to add neighbors OTHER than through Facebook! I am NOT, nor will I EVER add complete strangers to my Facebook friends list simply to have more than one neighbor in a game!!! It's been YEARS now and I know thousands of people have asked for other options to add neighbors, but still the developers refuse to do anything about it. I would gladly go without a few of the nearly impossible quests and hopelessly glitchy events if that was what needed to happen in order for them to find the time to code in a solution for Android users... but no... they just keep pumping out glitch filled updates loaded with quests that can only be completed in time if you play 24/7, new scams to lure people into spending ridiculous sums of REAL money for useless *, and lengthening
the time needed to complete even the simplest of tasks so much that all but a couple of hobbies are unbearable to pursue.
What a waste... to create an amazing game only to suck all the fun out of it and to frustrate and * off a huge percentage of loyal players by ignoring their complaints, suggestions and requests.
