If I use key-pressed in the arrival cues of a ship it seems to operate independently of any key-reset or key-reset-multiple SEXPs used in the regular Events Editor.
For instance, let's say I want a ship to show up after 15 seconds have elapsed and a specific key has been pressed, in that order. Using and-in-sequence I should be able to allow the player to choose when this ship arrives, provided it's no earlier than 15 seconds into the mission. So I put a key-reset in there to make sure the ship doesn't show up right at the 15 second mark if the key was pressed at an earlier point. But this seems to result in the ship not showing up at all.
Am I missing some technicality here or should I put this into Mantis?
