Vertex manipulated blocks modificating themselves when load/saving

[CubiC165[GER]]

so the problem is i created a boat with vertex manipulation but the front blocks corners move 1to20 HU over and over into the same spots? i tried turning them into entities/func_detail but it still occurs
is there s1 knowing the issue and having a solution or should i just recreate the front and hope it stops?

thx for ur help !

This happens when you make an invalid solid and Hammer tries to correct it. You can't have any brushes that a) are concave, such as an L-shape, or b) have a face whose vertices are not all on the same plane. To fix them, either move the vertices back to the way they were or split the brush into multiple valid pieces/triangles. If you're ever unsure whether the brush you just manipulated is invalid, just press Alt+P to bring up the problem checker.
