Anyone Here Creating REX Files with ReCycle? I Have a Question

I make loops. So I have a WAV file, loop it, and verify that it looks well - specifically, no clicks when it transitions from the end to the beginning.
 
Then I Acidize it. Still works fine.
 
Then I load the WAV file in ReCycle, and every now and then (maybe 1 out of 5 loops) there's a click when the loop transitions from the end back to the beginning. I've taken the WAV file and added fades at the beginning and end, as well as added a transient marker to cordon off a slice of silence toward the end of the file, but it seems no matter what I do some files have a click at the end.
 
In SONAR, you can add a fadeout and still roll out the clip to create multiple iterations, so ultimately it's not a significant problem. But I'm wondering if anyone has encountered this and whether you've found a solution.
