Hello! Thanks for the post. Please see the sticky in this forum about rules and guidelines for posting about issues.
-Are you hard crashing (app closes, returns you to home page) or soft crashing (game still running but you're stuck/inputs not being registered etc)?
-Which platform are you on, iOS or aOS?
-Which OS version?
-Which device? Which model?
-What are you doing leading up to the crashes? Is there a common thread, or does it just seem to happen everywhere in the game after a certain amount of time?
