I'm not sure if my problem qualifies as a gameplay issue or a technical issue, but....
After playing for two hours and taking screenshots using the C key, pressing the C key suddenly has no effect at all.
I can still, for example, use the A and D keys to scroll sideways, but the C key is dead.
The same thing happened to me after several hours of gameplay last night as well.
I know I could still take shots using the center bottom camera icon, but I usually press Tab before arranging screenshots, so the camera icon method is not desirable.
Would anyone know what might be causing this problem?
I tried a search at EA Answers HQ and a general Google search yesterday, but found no solutions.
Edited to add: Since my C key worked fine when I started my game today, I tried restarting my game just now and the C key is working again.
So I guess one workaround for this would be to save and restart whenever the C key stops working, maybe.
Edited: Feb.2018It sounds as though this might (?) be a bug. If you're experiencing something similar, it maybe a good idea to post about it in the thread linked below and click the Me Too button under the 1st post.
