Atrazine's Terrain Plugin doesn't save data after rejoining roblox studio

So I just started using the Atrazine’s Terrain Plugin for easy to make low poly terrain, but whenever I rejoin roblox studio after making tons of nodes and triangles, the nodes wont move with the triangles anymore, is there another plugin that saves data when you rejoin studio or possibly a fix to this?

You should contact the plugin owner about your issue.

I would but they haven’t updated their plugin in 2 years.

You can edit the source yourself.
