It is very common to find the small O ring in the fill valve to be compressed and rock hard in these guns, it's difficult to remove, be careful not to damage the seal groove in the brass plunger when you remove the old hardened O ring.
Stop that pigeon now!

Probably a bit of dust/dirt that got in your fill or exhaust valve and has now blown through then.
