[HSY] No vendor for thrift tea counter appears | EA Forums - 5044120
But for already-affected lots, you'll need to change the lot type to something else and back.
For the children not playing with toys, please make sure they have enough space for the interactions and their needs are high enough that they're not being pushed to do something else.
Since this is a multi-report with several existing threads, I'll lock it here.
