It appears that it currently takes longer than usual to process updates for the marketplace, so if you don’t want to wait for the update, you can do the following:
-download the 4.24 version of the plugin
-move it out of plugins/marketplace into a separate folder outside of your UE4 installation
-open Easyballistics.uplugin in a text editor and change EngineVersion to 4.25.0
-recompile the plugin like this: UE4 - recompiling plugins (Windows & Linux) - YouTube (requires Visual Studio)
-copy the packaged build into your game’s plugin folder (ie. MyGame/Plugins/EasyBallistics)
