[Therion] Problems with export .pdf file [metapost warnings]

Hi! After all steps to remove white trianle problem there is still the error: cp exit code 1. There are also some warnings in metapost log file like: Warning: the turningnumber algorithms do not agree. The current computed value is 1, but the 'connect-the-dots' algorithm returned 0 What does it exactly mean? Where is the problem that Xtherion still occures cp exit code 1 error and blocks exporting .pdf file? I've attached therion.log and data.pdf (generated by -d option) Best regards Piotr Szukała Poland
