2D Symbol Issues with Library Part Maker Objects since updating to 28.3.3

[Jeff Galbraith]

2D Symbols for library parts are no longer working.  Objects I create now in LPM or copy from other projects no longer have visible 2D symbols.  Now when I select the black dot and open settings the symbol preview pane says 'Invalid 2D Symbol.  Open the library part for editing and check it's 2D script or errors.'

The only thing I can think of that might have caused this was updating to version 28.3.3.  Has anyone else seen this?  Is this resolved in the most current update?

Does anyone know what to look for in the 2D symbol GDL code of the object that could be related to this?

Thanks,

Given that you mention the AC28 update, I am assuming they worked in an earlier update of AC28?
