Hej Gms0012,
the ID 447 is a terrain tile (#447). The table 'terrain_blocks' contains all recent changes for forest, geo (ground) and objects (like moveable and unmoveable objects) for each terrain tile. The decisive point is 'ObjectsVersion' from the table 'terrain_blocks' has to match with the latest 'Version' entry in the table 'objects_patch' for this specific tile.
Unless I'm mistaken, you've placed a
cog on your map, right? Could this be the cause of this error?
