Unable to Send/Receive Mail and Duty Finder 90000

Currently, I am unable to send or receive mail as the title says. Items are listed as "unique" or "insufficient inventory space," even if it is 1 gil. With that, I am unable to send mail as well. It's as though the entire mail system is broken. This all started when I randomly got 90000 the other night after having sent a piece of mail. The mail was returned to me, but the inventory slot was non-existent and occupied. Then it went away.

To make matters worse, I am unable to even join a duty as I receive 90000 upon loading and never connect. Walking into an instance does not change that (Which makes sense as it's also Duty Finder server), as I was suppose to be working on Coil T5. I assume this is also connected to my bug mailbox.

Currently speaking, I have sent multiple tickets in with 0 response as of late.

Does anyone else have a similar issue?
