Kerbal Crashes Through Terrain on Visual Inspection mission

[MattW93]

Hey everyone,

I've attempted the mission in question twice and I've so far lost two brave Kerbonauts to a Kracken hiding underneath the surface of Kerbin. While exploring the area Y-Y4 (one of three other tasks in the mission) I have had two Kerbonauts fall through the terrain and "crash." The first I had to walk a ways from the lander and he fell through at what I assume was the border of the mission area. The second landed safely, got out of his craft and fell through only when I attempted an EVA report to complete the mission. Any help in addressing this issue would be much appreciated.

Ok I managed to complete the mission after upping the terrain graphics from low to normal. It might have been because my Kerbonaut was stuck into the terrain halfway while he was walking
