Hi Alvig17,
your recent activities have left behind several broken relations:

https://tools.geofabrik.de/osmi/?view=areas&lon=-0.77313&lat=45.83813&zoom=14&baselayer=Geofabrik%20Standard&overlays=duplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways%2Cduplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways

https://overpass-api.de/achavi/?changeset=145715394

There are doubled landuse relations like the "Forêt de la Roche Courbon", relations with wrong role items (inner/outer) and landuse collections.

I strongly recommend to learn the basics of multi-polygon relations:

Additionally I recommend to use a proper editor if you like to deal with relations like JOSM.

Can you fix those errors please?
Kind regards
Guido
