Issue #22775: TreeAspenLog01.nif: Small seam on log mesh
There is a visible (but very minor seam) on a portion of the log mesh (see screenshot attached to ticket).
Someone on the USSEP Nexus Mods page reported this issue and I confirmed it in my game. To be honest, this is barely even worth worrying about. Maybe someone will feel like getting around to fixing it some day, but there isn't any rush.
