Creepy Ambience and Creature

Here is a current iteration of some spooky/creepy ambience with a creature inhabiting the space. There is something weird going on with Reaper and I can’t quite figure out why this is happening, but in a couple of spots, the ambience just cuts out for seemingly no rhyme or reason. Inside of the DAW it doesn’t do it consistently, but when rendered, it is both spots you can hear it in every single time.
