Bug report.
Entering mesh manipulation mode, I am served the following error messages:
Assertion failed (_SEIDEL_TRIA_lmpl.pas, line 1162)
Assertion failed (_SEIDEL_TRIA_lmpl.pas, line 340)
Assertion failed (_SEIDEL_TRIA_lmpl.pas, line 346)
Assertion failed (_SEIDEL_TRIA_lmpl.pas, line 1144)
Not necessarily in that order and sometimes multiple times.
After that quad remeshing doesn't work reporting:
Part preparation failed.
