Sampler Track Issue

Anyone else noticed this sudden bug with the Sample track?: I just opened a session to render out a final mix and suddenly the sample track sound is silent. After scratching my head for a few minutes I got it to “work” when I unticked the AudioWarp function. Which is not ok as I had the formant and sample speed set a certain way. Without it the sound is different. God damn bugs I tell ya! Happened to 3 different songs today. Anyone know a fix for this? I am in the middle of wrapping up an album and the sounds in question are the main lead for the song
