The island Abandoned Spaceship was made in November 2017 with IC 1.63. That version of the IC included a door that self-opened on approach. In a later versions of the IC, the-self opening feature was disabled. I'm thinking, other old islands might have these Saborian now no longer self-opening doors. For now, I fixed the island Abandoned Spaceship by replacing the closed doors.
