Oh~ my goodness! However, very well done mate for the game released. How did you go? Might be interested of knowing more about your interest later.
Well, I got a very good NEWs for everyone, including you & me.
I had already figured out the stuffed up issues from Epic Installation problem - in order to solve all the installtion problem:
" Just run the Epic Launcher online (with Firewall & AntiVirus on) and handon there for at least a few hours. All the unable to download engine/asset libraries/plugin problems as before, will begin to work like a charm. "
This is more likely show that the Epic Servers either have some installation scripting bugs or perhaps the worst, they may be compromised/corrupted by viruses/trojans for quite sometimes without notice- this would be really ‘a bad situation’ for all of us. I seriously suggest the Epic Technical Supports should inspect the issues as soon as possible.
Anyway, our problems are considered “solved”. Indeed, I believed this could also help thousand of people who have suffered from the same issue for months. At last, we can sleep better now.
Good luck mate.
Epic really got a big issues here…
