I am having issues with my UM3 where the final layers of a model are being flattened, distorting the final print. The print looks really good up the first few layers, and then the outer wall layers have large flattened circles, presumably from the extruder. I've manually leveled it multiple times, but it still seems to do this. The finer the layer height I use, the worse the effect seems to be.
Here's an image of a recent print, PLA + PVA for support with 0.04mm layer height.
* Combing is on all
* Retraction is enabled: enabled at at layer change, before outer wall
* Avoid printed parts and supports while traveling is enabled
* Z hop while retracted is enabled, only over printed parts

Any advice on how to prevent this?
