I have two plugins, Wwise and a Dialogue system, that were brought into the project at v.4.21. I need to be able to launch the project from a source build to have dedicated server builds. When I tried to switch the UE4 version from 4.21 to UE4-Source, then build it, then launch it, it told me those two plugins were designed for build 4.21. When I chose the option to load them anyway, the engine opened in an older version 4.20.3 (not sure why) instead of UE4-source. A lot of assets were missing and it couldn’t open some maps from 4.20.3 so going with that option won’t cut it. What is the best solution here? Is there a way to safely migrate those plugins so that they are properly opened with the UE4-Source build?
