DoN's 3D Pathfinding for Flying A.I. [Support Thread]

In the Epic Marketstore it’s saying I can’t install it as it’s max supported version is 2.23.
Now I want to ask if there is any access to the source files so we might patch it?
The plugin is sounds that it might be good for some occasions and see this as a real shame if the author hasn’t released the source code if he decided to just abandon it.
I have some experience in c++ and am a dev by day in c# .Net for 6 years.
Currently I’m working on a somewhat complex project in Unreal in C++ so I’ve built some exp in it and would give it a go for sure to upgrade it if given the chance.
