Over a week ago we rented a corporate storage at an alpha terminal, which expired a few hours ago.

When checking storage details, it says the lease is valid and the storage can still be fully utilized. The 'Pay rent' button is actually disabled, the expiration date is a few hours in the past.

Also, Another storage we have at an outpost (which hasn't expired yet) doesn't show any weekly rent in the list of storages in the corporation management window.

EDIT: the renting fee was withdrawn from the corp wallet a few hours later and lease extended with a week from that point (which gives us 6 hours free storage basically).
