This is odd. Is your vibratory tumbler getting the media moving fast enough? Are you using Walnut? (I run the pet store lizard stuff)
Are you putting too much lube on perhaps? I run Dillon lube and tumble off with no issue for 45-60 minutes. Never any clumping in the brass.

So I’m using the big Dillon tumbler with Cobb as stated above. I usually tumble the lube off for 30m or so. You think that may be too short?
I use a P/W auto drive on a 1050 as a dedicated machine to do nothing but case prep. I wouldn’t say to use too much lube (you can never use too much lube ) but I dump them into the bowl and spray then rake them around and spray again then run the feeder. I don’t feel like the machine is that gummed up or anything.

I'd bump it up to a full hour to see if that helps. 30 min in my vibratory is borderline for lube removal.

Walnut media from Harbor Freight works awesome in my experience, far less dusty than corncob.
Let the cases tumble longer too, I rarely go under 90 minutes.
30 minutes is the minimum amount i run it to dry the brass after wet tumbling.... even for drying that's a short run. I bet an hour cures your issues.

The more I think about it, the more I'm convinced another 30 min will do it. When I'm tumbling off wet brass, I get some primer pocket clumps if I try to short run the tumbler for 30 min.... and that's only water.
