I contacted GOG support and they recommended creating a THQ ticket (which I already did) and also emailing support@quanticlab.com (which I just did). I think it would help if everyone from this thread also emailed them, otherwise the developers might ignore the problem.

quanticlab? Are you sure? I am in close contact with THQN (see official SpellForce discord server by THQN) and this is news to me that a new studio got asigned to it.

For everyone reading this, please do only use this ticket system here.

I push your ticket ID's directly to the Community Managers and sometimes the producers if its critical and in my range of connection.

Well, I didn't imagine it. This was the email sent to me by GOG support as a result of my complaint. Copying their email response:

I think they gave you the "default" contact.

Has anyone heard anything ? I have not.

Something is in the works right now, but because of compatibility sync issues with the other plattforms, it drags a little on.

Hey that's good news At least it's being worked on.Thanks for the info.

Looks like it's fixed. I just had updates. I tested soul Harvest and it's good now. The rest are updating now. Thanks To Unreal_NeoX
