[Help] Mold growing on 1st ed base set zard...in a psa case

Hi guys, per picture, there’s mold growing on my psa 9 1st ed base zard, still sealed in case what would you do? Isn’t psa supposed to be airtight so how does this even happen? Merry christmas to me wtf, its such a high value card I stored it in a regular box like any other card imgur.com/a/3oDQ5LC Edit: I checked the rest of my collection and not a smidgen of mold in sight, seems like it was inside the case to begin with and grew. Would PSA be liable in this instance? [image]

Maybe helpful.
