In the class TreeLoader, in the method OnGameSceneLoadRequested(), there was a condition that limited a custiom tree loader at mode Career. I had in the condition the mode Science Sandbox. The rest of code worked for both modes. I only had the TreeListItemData class, that was missing in the giving code. PS : I'm French, and I don't speak English. So I'm sorry if you find mistakes.

I decided to change the source code and compile the plugin. Finally, this is working ! I don't know if I can publish the plugin updated here, but I put a link here. If it's forbidden because I'm not the owner of this plugin, delete this link : Tree Loader Updated

I have just a question. How do a custom tech tree in Science Mode, introduced by 0.24. The popup doesn't appear when I launch a new game.
