I see. So I think it is fair to say that this was a scam. they used us to get some money to keep their development going and promised us continuing support and now they are openly breaking the contract. Well they probably know that nobody is going to sue them over 80$ so they figure they get away with it.
I guess I stick with my UE 18.3 installation here as long as I need to do some LOD work or I will check out new UE versions with Instalod before I remove 18.3. I just hope Epic will support skeletal mesh reduction. I mean for a developer good at math it should not be too difficult especially since the Instalod source is available to everybody to have a look at.
It’s a good warning for the future not to trust companies anymore that promise you a deal that sounds too good to be true.
