Invisible, un-attackable units on train station map

[Blehs]

So ive had this problem for a long long time now. Basically it happens on the train station map. All the people that you can hit are invisible EXCEPT for their shadow. So basically ive got these black dots (shadows) moving around the map.

Another weird thing is that occaisonally these dudes will appear for around 1/3 of a second, disappear for another 1/3 of a second, reappear for 1/3 of a second and so on. This goes on for between 2-5 seconds (the time they flash seems to vary). This is the only time i can hit them.

Ive tried contacting Gree a long time ago about the problem, but never had anything done about it. Can anyone help me out?

While I don't have this exact problem ,I do have a problem with attacking rivals on my llp account. Like you I get black dots (shadows) instead of players. My llp is on an iPhone 4. I have no such issues with my main account on an iPhone 4S
