I've noticed this over the time of my playing, but when I play some modes, my offset is fine, but then when I play the other modes, my offset is.... As you'd say, off. I've changed my offset many times and I've realized that my offset for osu!mania+Taiko are different for osu!+Catch The Beat. Currently, I've found my osu!mania+Taiko offset to be 8ms, then I found my osu!+Catch The Beat to be 4ms. I tried getting past it by using the local offset when I'm doing standard or Catch the Beat, but 5ms is just too big of an increment and does throw off my play. I think an option for separate game mode offsets would help a lot because I don't wanna have to keep going back and forth just to play standard or mania.
