When Getting all the Agent Equipment...

the finished hat with +3 on all had an expiery date too
and i put it far away from the others before dropping, so i dont accidently drop it
well, getting that hat again takes 30mins
i might try to it to check again, but im 99.9% sure the final hat got an expiery date too

My one doesn't expire (3stats to all, 10HP, 6slots, level 30 req.)
