Problem Details:

I have no clue why
https://osu-ppy-sh.tvgratuite.org/b/1673578?m=0

Starting at 03:09:293 - and 03:24:902 - in insane I have a pattern that looks like this:

pastebin of the .osu where the pattern is as I intended it: https://pastebin.com/qwkgYDsP

but for some reason, when I work on other completely unrelated areas of the map, do stuff, whatever, I haven't figured out exactly what's triggering this yet, I'll go back to the pattern to find that osu added nodes to the sliders of its own accord (again: I never touched those sliders myself.)


pastebin of the .osu, where after other changes, I found the sliders messed themselves up again: https://pastebin.com/8NGiC1uv

At first I thought it was weird, but it keeps happening to this specific pattern in this map and it's incredibly annoying to have to re old versions and change it back to how it was supposed to be. And it's consistently messing the sliders in these patterns up.

Please fix ; - ;


osu! version: 20180626.1

Bumping to add more details as I've finally figured out the exact causes of this issue:
AIMod.
If you open aimod, pressing refresh will progressively add more and more nodes to sliders which are perfectly stacked at the heads. There must also be unsaved changes in the map for this to happen where it continually adds more and more nodes.

Here is a video:
after I saved the beatmap, I hit ctrl+L to reload it, causing it to render the sliders following the added points. The sliders do not reflect the added nodes until the sliders are manipulated or the map is saved and reloaded.


this happens on both stable and cutting edge.

this is a concerning issue as when it happens on regular completed maps, it can be very difficult to catch as it is not a change made by the mapper or modder, therefore they would not think to double-check affected objects, because as far as they know these should not have changed.

Fixed in the next cutting edge build.
