Using version 2.1.8HR1.
I have an album with title ending with "...".
At some point, CUERipper fails saying that it doesn't find "a part of the path".
I removed "..." from the title, it's now working.
I can confirm this Issue. On CueTools 2.17 I've never had this Problem.
Instead of deleting the three dots from the title, you could use the Ellipsis [1] Unicode character "…" instead of the three dots. In this case, the "…" will also show up in the path.

CueTools 2.17 was removing the three dots at the end of the path, without user intervention. Somthing has changed, so CueTools 2.18 can't handle this.
In the meantime, a fix has been prepared for album titles containing three dots at the end.
Feel free to test the updated CUETools build found here:

Bug is still there in version 2.2.1.
