Status on the latest update:
Device: iPad Mini (1st Generation)
iOS: 8.1
MW: 4.5.2
Content: mw 20141107 42642
Build: 452.4.1
Internet connection: 100Mbps
The problems still:
1. Game loads about 5 times longer than normal
2. Lag or pausing or freezing, every minute or two and last for about 20 to 30 seconds
3. Invincible NPCs still take time to load. Maps taking longer to load all NPCs
The only good thing:
1. Game does not seem to crash randomly when viewing Inventory, when selecting filter or sort
2. Stats are displayed correctly before receiving the first temp bonus and after getting the first temp bonus
Seems like Gree got 2 out of 5 problems corrected for me.
But the load times and lag or pausing or freezing (whatever you want to call it) has gotten worse.
I still need to keep an eye out for the data usage and see if that has gone up.
UPDATE:
I spoke too soon. My stats displays incorrect sea attack once the temp sea attack was added on to my stats page.
My permanent sea attack bonus now shows the same number in my temp sea attack bonus.
I guess Gree did not fix the Stats Display after all.
