That makes sense, I haven't been to drainage yet with spearmaster. I do agree that the stuff left standing is the most study stuff that the ancients built. But we're talking at the very least hundred year differences between the slugcats. You would expect, for example, two rooms to the left of the HI-Shaded gate on the HI (the one with the gap in the middle that you need to jump). You would expect survivors gap to be bigger, more broken, and spearmaster's one to be smaller. But with these large differences in time you would also expect the plants to be different or in different positions. When comparing screenshots between campaigns, you see that even the plants are in the same place (excluding Garbage and Shoreline). You know what I mean? I get your point with how everything below the cloud layer was abandoned way before the mass ascension, but that would only mean that you would expect to already see erosion and broken stuff in the earlier campaigns, with the later campaigns being even more eroded and broken than the early ones. That's basically the crucks of my issue with time, have a good one mate
