Annoying node bug......
Jumping puzzles, love them or hate them, I hate them. Thread killer.
Those are available node placements. The nodes haven’t actually “spawned” per se, so it’s just visual error. They got rid of some of them by removing the Raw Candy Corn nodes in the most recent patch, however other nodes are still visible for a split second.
If you keep running to these fake nodes, try pressing Ctrl or Alt when you see them to verify that they are there and check your minimap.
