anyone else having trouble with Vallejo Paints lately?

[Dr.Falkenhayn]

i have used Vallejo Products for Years now,never had any Issues until now: My new Bottle of crackle Medium doesn't crackle,the Matt Varnish leaves a semi glossy Result,the Black-Grey Model Color (Vallejo 70.862) is brighter than my old Bottle and finally my new Bottle of Foundation White is more a Paste rather than a liquid Paint 

i got these Paints from different Sources,i know how to work with Crackle Medium and i know i have to shake the Bottle well before using 
Whats Happening?

That crackle medium is behaving a bit erratic, though the bottle I have is a bit older.
Can't say much about newer paints, haven't bought any recently. Would be quite sad if they'd managed to mess up the Surface Primer as well, I really like that stuff.

Bought a new bottle of Black-Grey not long ago (2-3 weeks) and it looks the same as ever, ditto Foundation White. Never used the crackle medium.
