Retop (Retopologize) breaks Navigation on landscape tile

Heey all!

We have experienced a nasty bug where as soon as you Retop a piece of landscape it will break the whole navigation on that specific landscape tile.

We know that te Retop can be removed with: “RemoveLandscapeXYOffsets”.
But does anyone know how these two can work together??
There is so little to find on this topic, can anyone help??

(Also if you use DynamicNavmesh with invokers it still breaks the entire landscape tile)
(To reproduce this just make a empty world with a navmesh volume and landscape and then Retop a piece of landscape)

With kind regards,
Alex
