I have noticed that the spam wave list isn't ordered properly. Previously the level 1 scams were at the top, and level 80 at the bottom. Now it seems there was an attempt to order it in reverse, with level 80 scams at the top and level 1 at the bottom, but the vacation scam is in between level 80 and 60 scam waves while being a level 40 scam. From what I remember investment scam used to be at the end of the list, so it should be right at the top, not below romance scams.
I have already disabled TornTools and Tampermonkey to check if it was the browser extension's fault.
