Some issues that I'm having.

I am having some issues while playing sims freeplay:

1. The roof and external walls tabs isn't working for some houses (especially the multi-storied ones). When I click on the tabs in home store, it either: a) opens to a blank page, b) doesn't show all the options, c) shows 7/8 options, but if I select one and then cancel it- then shows some other 7/8 options (and the circle repeats).
2. I usually keep the lights on the outside of any houses on "night light" mood, and the inside ones on "sensor light" mood. While the inside ones work fine, the outside ones seem to have a mind of their own; no matter how many times I change it, the outside lights keep turning off/ don't remain lit/ don't remain lit even after I choose the "turn on" option (where it was supposed to remain lit 24/7).
3. The game keeps freezing for a few seconds. I refresh my phone, clear the caches, but the problem persists.
