Please find attached one of my design files that has this problem.
Symbol "RES" has multiple IDs - easy to see in text editor. I think, this
started happening when I edited the symbol in the library (made pins shorter)
and tried to update symbols in the schematic. I think, every time I updated a
symbol in the schematic, TinyCAD created a new symbol definition.

It is very difficult to clean this up, because symbol IDs are not umque,
complete;y different symbols in the schemtic often share the same ID in
SYMBOLDEF section

Thanks.

locate such a problem, please send me a copy of the design file and any
information that you might have that would allow me to reproduce the problem.

As a result, sometimes pins get disconnected from wires, especially when I
copy/paste schematic to a different file.
