52g slab not finishing.

Alright so I blew some bud and ended up with 52gs of shatter. My problem is that I have been purging this for 2 weeks now. I've probably pulled vac over 20 times. I've rolled it into a ball and flattened it out about 6 times. My heat is always at 102. Every time I pull a vac I get a bubble reaction like it was just blasted.

I've done over 500 runs and never had this problem. I thought it was because it was so much but I split it up and only purged like 10gs and it's still going.

My other batches would be done in no more than 3 days with maybe 5 vac pulls.

It will stay like that the whole time. All my other batches will become clear with no bubbles when it just sits there. And it is like shatter right now. Not gooey at all.
