Unfortunately I can’t build my project with 's June 10th Victory Plugin, but it works with 's quick fix. I also did reparent my own GameMode to the regular GameMode class. I wish I could copy the error log, but it dissappears as soon as the error message pops up telling me to try rebuilding from source.
The following modules are missing or built with a different engine version:
UE4Editor-VictoryBPLibrary.dll
Would you like to rebuild them now?
