Game crashes are pretty serious, let's see if we can solve it:
1) What's the RAM like on your device? Sometimes recall scroll will put someone over their RAM limit, forcing a crash. Not likely the case here, but clearing your cache etc might help.
2) If it's a test version issue, it really needs to get looked at by the Developer. Reminder to post all test issues in the tester feedback thread, linked below.

I'm locking this thread and posting a link in the tester thread so the matter can be reviewed sooner than later.
Fingers crossed there's a simple, easy fix.
UPDATE: Per Developer the recall scroll crash "happens because it tries to recall to Whitetower, which isn't there yet. It will be automatically solved with next update. "
