Navmesh Graph with GraphUpdateScene Tags

I’ve read in the documentation perhaps it’s only possible to change penalty and walkability on Navmesh Graph? I didn’t really manage to get that working so I tried tags instead which seem to work fine. I have two major issues with GraphUpdateScene when trying to change tags.

First is that on run time, after some non-specific time, the changes made by the GraphUpdateScene scripts disappear (as shown in the video in the link)

Second is that when I run AstarPath.Scan();, the outcome is different than when I scan the graph by the “Scan” button in the editor (Scan() is run everytime I place a building down as shown in the video).

Any tips? Should I leave the tags and rather try to make the penalty changes work? And if so, I wasn’t really able to get RichAi + Seeker react to the Penalty changes of the graph. How would I go about that?

Thanks and happy holidays!!
