I got a message on my iPad the other day about storage and my game was around the same size as yours. I was like you, worried about uninstall/reinstall in case I got the load bug too. I was braved though and went for it and was OK. My game size is now 1.22GB. However, I am getting the lag that the last few posts have been talking about even after reinstall so I am not sure if game size is the cause of it.
I am a bit annoyed the crashing when using Troopers seems to have come back. Had a few months pretty much crash free but now getting a lot more crashes![]()
