This looks like both mods' river-traversibility-improving strategies combining a little bit too much. I'll look into what the right solution might be. I would like to derive a formula that chooses where the river shoreline occurs and ensures the terrain always reaches the water level at that boundary. I think that will solve a lot of river-related concerns in the long run.

Update: The current plan is to introduce reworked biome layer generation which would remove the need for the current sampler which produces these shapes.

I will also look into quicker fixes in the interim, though.
