Boom's linedef special 260 allows a 64K
translucency lump to be applied to the
front sidedef's midtex for applying a
custom 1 to 99% translucency value. Stop
reporting this as an unknown texture.
Changed, Sectors mode: "Flip Linedefs" and "Align Linedefs" actions will no longer flip single-sided linedefs with only front side.
Fixed, Script Editor: fixed a crash when trying to update script navigator combo box when switching to a never saved ACS script.
