I am currently using UE 4.12.5 version.
When I start my project in the file system(.uproject file), It stops loading at 72%.
However, when I start my project from Visual Studio, it works.
I narrowed down the problem. if I remove my custom GameMode from Content folder, Editor loads my project successfully…
But, I need that blueprint to work my project!
So, How can I fix this problem?
P.S I ignored “CDO constructor” problem for my custom GameMode.
Thank you SO much for this fix! I had a very similar issue with my custom player controller & game mode, seems to be a circular dependency issue. I wish UE4 told us about this issue when it arises rather than infinitely loop.
