When will Humble Bundle resupply the Under night Inbirth 2: Sys Celes keys?

HB and resupply?
For ex. Poly Bridge is "temp" out of stock for more than 2 years.
If lucky - sometime or also maybe never. But with price glitch it may be different.

Keep in mind that the generation of keys is limited by Steam. So even if Arc System Works is okay with the glitch, they might need to stock up keys first. On the other hand there were also price glitch cases on Humble with forced refund and revocation of key (if provided). Time will tell.

Commonly they refund price glitched purchases.

I bought a game on 09/11/2018 and I'm still waiting for a key. It was a game in a bundle back then. And I have written to the support more than once.

Humbel will eventually restock their keys to sell, but it doesn't guarrante you to get a key, feels like they restock full price and wait for high sales/bundles if devs give them cheaper ones to send already sold ones.

And i am waiting for my Roboquest also for some time..

I got 2 orders.

They canceled and refunded my out of stock order.

They have not touched the order I redeemed (before keys were exhausted) yet.

I bought it when it was out of stock and they refunded me. Still benefited from the deal though.. I wasn't subbed to Choice and because of that they gave me $1 wallet credit for the purchase.. which I used on the Agents of Mayhem price mistake. Basically got Agents of Mayhem for free because they didn't cancel that order. Funny how NOT being subbed paid off.

If it wasn't obvious to some people, Humble gives wallet credit instead of a straight discount when buying from their store if you aren't subbed to Choice.
