Trade issues for Lean Hogs

I’ve had several trades for Lean Hogs (futures symbol @HE) disappear (I assume expire) randomly. I am not sure if this is an issue with trading hours or something else, but they trade 24/5 starting Monday at 10:05 and do not stop until Friday afternoon yet my orders expire I believe overnight. I had an order today which filled in my real account but is missing from the C2 system without filling. Can someone verify the setup for @HE?

Sorry to keeping “hogging” the forums with my questions about Lean Hogs, but I’m hoping the awful pun will get some attention…

Please email with exact system ID and details about the trade that expired which you believed should not have. - MK

Will do next time I see it – don’t remember the details unfortunately. Thanks.
