My map is full of info_nodes...to prevent NPCs from getting stuck anywhere on the map. I just granted them access to every point on the map, however...there is a point where these weird white and red particles rotate. I'm thinking it might be the cause of many info_nodes in one place. But these particles always don't appear. They appear sometimes...So when I delete the info_nodes then I can't be sure of it, if they were the cause.
Took a little screenshot of that point, Help would be appreciated.
