Started looking into the problem with walking up that specific stairs: https://github.com/ksterker/wastesedge/blob/master/models48/map/building/stairs/wood/stairs-back.amdl
No clue yet what might be causing it and how to actually debug it. Looked at the verbose collision system output but could not spot any obvious difference between that one and any of the others. Might need to dig even deeper, but might also be something entirely different. If it is indeed a problem with collision, one possible cause might be that the backward faces are wrongly orientated. Might need to write a unit test to ensure that this is not the case. OTOH, I would assume that the first collision occurs against the vertex along the back upper edge of each part of the stair, so face orientation should not even matter, Will give it another shot tonight ...
