Katarina's auto's stop after shunpo

When Katarina uses shunpo (e), her basic attack resets. When you have auto basic attack on, she should automatically his the last selected target, or whoever's close by. However, for some reason, she freezes, and doesn't do anything more until the summoner tells her to do something else. So to summarize:

• basics are set to auto
• Katarina shunpos
• Katarina stops with her autos
