Hello,
you changed the coordinates of node 7804196326. This node is part of several borders like Cameroun, which are broken now: https://www.openstreetmap.org/relation/192830#map=18/2.28293/12.16359. Border must not have intersections. The same problem with node 7804194876.

Please do not move nodes, that are members of borders, create new points instead.

Can you please fix this issue?
