I bought a lot of resources from the publisher 3D Voxel and Aniworld Design a month or two ago (about 30 3D model assets), and downloaded two or three after the purchase to see if the quality is ok, but I didn’t download it for the time being. Today, when I wanted to download the rest of the resources, I found that almost all of them were Unavailable, and the resource page was gone! That’s right, the two publishers have gone, what should I do now, most of the resources I bought have not been downloaded, and I can’t download them now. I sent an email to Unity support for many days and there is still no response. So Who can tell me how should I do to get the assets? Are there any guarantees for buying assets in the Unity asset store?
