I went to Aqualis to set up a temporary base, then went back to Humble to gather resources. I got sidetracked, and by the time I returned to Aqualis it was 40% into the Water Plants stage, which is fine, but I immediately noticed that the two western islands were still submerged. I checked the save file, and it lists "StoryEvent-Aqualis-Island (#)" for three islands, #1, #2 and #3, so it looks like events #4 and #5 were never triggered, even though the terraformation index is well beyond the trigger point for both. Am I missing something, or is this planet just broken now? I'd really like to fix this, because it's kind of ruining the whole game. Any ideas?
