hmm, where before there was a pause, now there's a 'pop'!
did you just remove the last frame and cycle? if so, it might be better to have that frame but set the cycle to be a relative number of frames backwards - was your last frame the same as your first? you should be able to move the playhead slowly and not notice any two frames the same (like you had before) or a larger gap than the rest of the loop (like you have now)
