Apex clothing causes texture map errors and terrifying scaling issues

When adding apex cloth to a skeletal mesh i’ve been getting some alarming issues. For one thing, it seems to immediately invalidate the UV maps i’ve assigned to my clothing objects, leaving the textures I have projected onto my object as if they were cylinder mapped. It also tends to deform the clothing to insane levels, either pulling it below the ground plane or dragging the entire mesh up into the air like some kind of 100 ft diameter death pincer. I’ve tried testing it on single vertices and have the same problems. Has anyone had similar issues?

with apex clothing applied (yikes):

I have the same issue - bump!
