First of all, where do you get the "it has been mistakenly linked with Isen EM list at last CV event"? Where do you come out with the idea that this bug only happened during last CV event? For your information, even if someone sealed something from Event Server at day 1, it works.
Second of all, I lol at you trying to act smart giving GMs a list of possible items that can be sealed (since GMs are dumb they don't know what items they have put on the event server that can be sealed, right?) lmao. Also I'm loling at you saying what does those packages include. Thanks for pointing the obvious, we didn't know.
Anyways, you forgot about the crone too. Since Isen is all about Crone and Power Badges, crone can be sealed & sold too.
