Anyone know what caused this glitch and therefore how to avoid it in future?

It's a graphical glitch that doesn't effect the gameplay by making you worse or better at it. They have bigger bugs to fix that should be a PRIORITY, like the game freezing bug when the next screen is loading, like when you're trying to do a battle in TB and the damn screen freezes and you lose your team because the last big update broke something and EA customer service thinks it is OUR fault because it didn't happen to them when they tried so they close every ticket because it's a player issue not theirs!
