So I accepted the quest, came to Kalix, talked to her, then talked to Edis, then nothing happens.

Edis says I can board the balloon if I buy a ticket from Kalix.

Kalix says IF I purchased a ticket, I should show it to Edis.

Kalix does not have any option to "buy", I assume a ticket was granted to me during questline, and this ticket does not exist in material form somewhere in inventory.

Balloon never lands, I've been standing there whole night.

I'm 61, finished Balenos, Serendia, Calpheon, and Media MQ.

Yes, I tried forfeiting the quest and accepting it again - nothing happens.

Yes, I tried to run on foot to Kamasylvia and talk to NPC there - nothing happens, "balloon" stage is mandatory, it seems.

What should I do, wait more, how many RL days?

How long this questline exists, if its a bug - why it is not fixed already?

Did anybody else experienced this problem?

Kalix gave you ticket, so you should have it, if you don't have ticket you can exchange it for blackstone (not buy).

I bought new ticket.

It didnt work first time though, I still consider this a bug.
