I'm uncertain about the reason, but it seems that when the Appsumo deal is associated with a team, it can be lost if you attempt to change or delete the group to create a new one.

Therefore, WARNING!! when creating an Appsumo group for the first time, with the intention of keeping it permanently.

I made the BIG mistake of accidentally deleting it, and now I CANT find any support from the illa Cloud team, except for a vague suggestion to go to Discord.

I do understand and appreciate the open-source nature of the tool and the efforts of the teams behind it. However, connecting a deal to a volatile team might result in more disappointed customers. Instead, they could have linked the deal to an un-deletable easily, unless you explicitly request its deletion.
