Hi kolivere, the amount of nodes on this object were not excessive. Removing detail poses little to no benefit in this situation. Please make sure to only simplify objects that have an excessive amount of nodes node.

A good example of an feature with too many nodes is this small building in California, which contained 339 nodes.
