Ties are bugged now???

Sometimes, when I do a tie between a chord (it's been with 4 notes, so far) the top, second, and last tie will function normally, but the third tie will go crazy: It becomes enormous - linking to somewhere random further back in the document (I use the continuous view), I can manually edit the tie to look more normal, but that's obviously not how it should be functioning and I thought I should say something haha!
