Thank you very much for you time and info. The problem what I'm still not very good with git command and it's sub commandants (git checkout and etc), so I stuck a bit there. But now cloned, changed to 6.9.1 commit number, builded, packed to local package and installed. Everything working fine. The crashes what I've encountered early based on mod files and changes in new OXCE 7.0 version. Let's wait while author of the mod will check it and made necessary changes to make it compatible with 7.0.
