This one's pretty simple.
You know how when you play converted 2b maps in mania, instead of the conversion engine moving the overlapping notes to different rows, you get notes inside of long notes which are impossible to hit. If you want a few examples of what i mean, try playing the loved transform aspire, tewi park 2b, graces of heaven, Jakarta funk brothers - insomnia, DJpop's Marisa Wa Taihen [TAG4], or Axarious' mashed potatoes in mania (doesn't really matter what key amount but it shows best on 7k).
I think this is really broken and bothersome for perfectionists trying to get an S rank or FC on these 2b maps.
