From Roger James, "Here is a small fix for the ac3d plugin geode.cpp. The fix is entirely localised to ac3d::Geode::OutputTriangleStripDARR.

Browse Source 
It resolves an issue when processing a DrawArrayLengths with multiple lengths where the vertex indices were incorrect for all but the first chunk."
