Why is my urban decay so shit now

I’ve been usuing the urban decay setting spray for a couple weeks now. Litterally no complaints, it left my base flawless and it lasted FOREVER. But the past couple times I’ve been doing my makeup it’s been like almost melting it off?? Everytime I use it now my concealer gets really patchy. I haven’t changed my routine at all so I’m really confused. Has anyone else gone through this?
