Profile view: terrain model breaking up when complex alignment exceeds a certain length

Hey,

I recently got my hands on OpenRoads Designer 2022. My issue is as follows:

When I create a complex alignment and open a profile view with an active terrain model, the terrain model appears to be fragmented (see pic). This happens when the alignment exceeds around 1400m in length. When drawing a straight alignment it seems to work a bit better, but fragmentation starts occurring after a certain distance. The terrain model itself has dense triangles, so the fragmentation isn't a result of void zones in the model. This problem doesn't appear in the 2021 version.

The terrain model used has been updated to ORD2022.

Any help regarding this issue is much appreciated.
