Okay, so I tried on a New clean project. I downloaded the NPCPathFinding2 Ver.20251226.zip. Then I tried to enable the plugin via an event using C# Program Assignment. Nothing, it does not work, but if I do download the old version and put it in the Script folder just like I did with the v2 file? It work, but with the old plugin commands ONLY. So yeah, I don't think your update is working, your v2 update use a .csrbr file instead of a .cs file extenstion.
Correct me if I'm wrong? I am supposed to put NPCPathFinding2 Ver.20251226.csrbr In the Script folder, no? Because that did nothing for me.
