It seems on certain maps, slider ticks are being generated where they aren't supposed to. So far, I've only found one, but I can confirm that this isn't an issue on stable and beta builds, only Cutting Edge. And it was not a problem yesterday. Just started today.
The map in question is
https://osu.ppy.sh/s/311013 Difficulty name is "Ouroboros Division".
Here are screenshots, with screenshots under that of how they should normally look, as well as timing points for each underneath that. There are probably a lot more in this map, but these are the ones I noticed immediately.

00:08:352 (2) -

So far, this is the only map I've seen this happen, but if I find any more while playing, I will edit my post with more examples.
