Problem
Feature properties.objtype uses short codes "n" and "w" instead of the expected full names "node", "way", "relation".
The LoCha component type ObjectType is defined as 'node' | 'way' | 'relation'.
Example
/api/0.1/projects/espana_navarra_aquitania_emergency/changes_logs.json, entry [3], feature bw155167573:
Expected: "way"
Values found across all entries: "n", "w" (no "relation" / "r" observed).
