The wipe is doing what it is supposed to be doing. Multiple instances of the same piece overlapping in the same place are merged into one, while cross formations with fence foundations will get one of the pieces in that formation nuked at random, which could cause problems down the line considering some people relied heavily on this structure. Also, new rules for building pieces have been put in place to avoid using the middle socket in fence foundations.
Our first announcement was initially vague as it wouldn’t affect legit constructions too much, but it caused some panic so we tried to explain it even further. Additionally, we’ve been refining the script that ran this “wipe” for a week, so it is even less destructive now than what it was initially.
