Just want to add my issue here:
Last night, I played simcity buildit on my iPad. I purchased many buildings, one of the major buildings I purchased was the community college requiring 10 keys (I think) and a deluxe fire station. Then, I played it again this morning to see my progress. I was able to rack up 80k population. My choices in the Global Trade HQ has also changed as I can now buy Vu-themed items. I was surprised by this as I haven't even reached 90K as it is the requirement to build Vu-themed items. (This is to make sure that I am connected to the internet)
This afternoon, I opened my game on my iPhone and now my cities is screwed up. It looks like the save game was reverted as the buildings I bought last night are missing. The population is now down to 42k but the screwed up part is the cities keys amount reflects the amount from last night. I checked warehouses and it also contained Vu-themed items.There is clearly something wrong with my game.
Here's the thing... some of the changes on my iPad is reflected on my iPhone. One best evidence of that is the Vu-themed items. The fact that I got those items showing on my iPhone yet my buildings are not there and my population is down to 42k, then there must be something really went wrong.
P.S. The game version in my iPad is older (Dec 10 build) than the one in my iPhone (Jan 13 build) as my iPhone automatically updates my app.
