Confirmed in sandbox.
Steps:
1. Create an Event, set the price with a price set.
2. Use the "Copy Event" button to make a copy.
3. Event info, Location, etc. will be duplicated but when you check the Event Fees options Price Set will be at "none" erroneously.
I'm not exactly sure, but it looks like the relevant record in civicrm_price_set_entity is not being duplicated.
