Hi buddy, sure thing. I made a quick tutorial for the "snow and Ice" pack that addresses this issue. For some reason ( I'm assuming the limitations of the engine in respect to character interaction) the characters can not transverse raised segments. Whereas they have no trouble at all on the flat surfaces.
To resolve the issue requires a bit of creative, but simple level design. Areas that you wish there to be character interaction, should be made using the flat normal segments.
Here's the tutorial.
I've developed a new philosophy... I only dread one day at a time.
