SWGOH - Game froze iPhone during Rancor battle. Restart of iPhone as consequence

[thedarkjedi1]

Today, around 7:40 CET, during Rancor Raid battle Tier 6 in stage 1 my phone (iPhone 7 with latest iOS 10.2) froze when running the game. I have been playing about 30 minutes with no problems before it happened. It froze after the rancor performed its move. Can you please check what went wrong. It is very disappointing when you played successfully for 30 minutes and the game crashes.  My ally code is 183-648-393 - slowdaywalker.  I tried to take a screen shot but due to the frozen phone I could not do so. Thank you in advance for looking into this
