Osmose issue 3210 refers to a problem in OpenStreetMap data where a way (road or path) is marked with the noexit=yes tag, but it has multiple exits or connections. This tag is typically used to indicate that a way has no exit at its end, which helps in navigation and routing. However, if the way has multiple exits, the tag is incorrectly applied and need to be fixed.
If the situation is as described, you should place the noexit=yes tag on a node at the end of the street, not on the entire street.
