KSP 1.10 water landing no longer possible...?

[Kilo60]

My spaceplanes hit some type of collision wall several meters above the ocean water surface now and bounce uncontrollably several meters above the surface when stopped.

 

Is this an issue with OST Spaceplane parts, the bouncy mod or something else?

 

Thanks!

Two things come to mind. 

Do you have Scatterer installed and the ocean settings haves waves interacting with ships? It makes it pretty difficult to launch seaplanes. It can be turned off in the settings. 

Another mod that impacts this is the new Kerbin Weather Project. If it is not set to ignore winds below 50m for landing and take offs a good cross wind will cause issues.
