[Therion] Problem with dots in symbols: map-connection is empty

[Benedikt Hallinger]

Hi there,
we noticed some problems with dots in symbols yesterday, the won't show 
anymore.

I can reproduce this with therion 5.4.4+19eb624 (2019-12-09).
The problem exists with the default symbol for "point map-connection",
as well as with my custom layout code for clay:

----------------------------
code metapost
     % --- CLAY ---
     beginpattern(pattern_clay_AUT_HVHO);
       % Just draw some fixed points on x/y coordinates
       pickup PenB;
       draw (0.20u, 0.30u);
       draw (0.35u, 0.70u);
       draw (0.40u, 0.40u);
       draw (0.60u, 0.50u);
       draw (0.80u, 0.10u);
     endpattern;

     % overwrite default symbol with custom one
     def a_clay_AUT (expr Path) =
       T:=identity;
       %  thclean Path;
       %thfill Path withpattern pattern_sand_AUT ;  % original
       thfill Path withpattern pattern_clay_AUT_HVHO ;
     enddef;
----------------------------


Has something changed recently in the point definition?
I assume, because the default map-connection item should still work but 
doesn't show points?


With best regards,
Beni
