Has anyone had this happen?

The last few pieces I've made have this weird effect when they cure. Has anyone experienced this or have any ideas? I've made pieces before that didn't look like this. I can't recall if I was using the same resin or not. The brand is deep pour Epodex, the room that I pour in is about 68/70 degrees on average and doesn't fluctuate too much. I know that it's thoroughly mixed and I use a heat gun to get rid of bubbles. I've reached out to the manufacturer and just haven't been able to come to any conclusion. They're smooth and crystal clear, then when they fully cure.. they look like this 🥲
