latex based adhesive in a latex tube will stick the insides of the tube together if it's left flat for any length of time. At least with butyl tubes/stans or latex tubes/non latex sealant you have a fighting chance of them not sticking together.

I thought that if you putting the sealant into the tubes you want to ride them, not to keep them deflated :)
Maybe that was the reason I've never had sticky issues with my tubulars.

I used to have race wheels and training wheels.
Race wheels got left in a wheel bag when I'm not racing.
Sometimes they got left for a few weeks.

What brand of tubs?
Did they have sealant in them? What kind?
And what exactly occurred after the few weeks?
(just asking, your story seems incomplete)

Tyres/tubes/tubulars lose pressure over time.
Eventually they go flat.

The latex sealant sticks the insides of the latex tubes together. Them when you try to pump them up, the tube tears.

I use my tubs often enough that they never go flat.

That's nice.
I have enough variability in my local rides/races that one set really won't cut it.
