Random crashes

The game seems to be crashing evey few minutes now. Even if your not doing anything, it just crashes.
Yes, I'm using version 9.12

I am experiencing crashes a little differently.

I have some crashes now when in World Map and Tavern. (In previous version, there was brief moments of being stuck, but no crashing.)

Edit: Also intermittent crashing from City Management tab even though it works better now.

Same crashing as Chicagoguy reports below.

Mine seems to crash when I have new mail, change cities, browse map, or just sitting idle.

Switching between City Management window and Dispatch/Transport/Enter inside this window and the functions within seems to heavily tax the client and causes it to work slowly and/or crash.

0.9.1.4 improved this from previous versions, but you might want to look at this some more. Devices like iPhone 5 and newer likely have less problems with this.

Other symptoms that occur with heavier activity of the client include the device getting hot, and increased crashing frequency. Allowing the device to cool down or resetting the device helps restore better functionality and reduce crashing stemming from use of City Management and troop dispatch.

Using iPad with iOS 7 seems to be fine.
Just getting a lot of lag lately.
