Deleted 50 million shipment

I spent the last 2-3 weeks saving up, playing a few hours a day after work to make my shipment...

Got commandeered, okay, i have 100M+ DPS, i can one shot the guy.

Go in, instantly click portal by accident, 50 million shipment gone.

There needs to be at least a warning.

Is there any way to re-open the portal? I was in there for 0.25 seconds...
