But let's stick to the "plan"...
- Game version — X4 beta 378025 (English localization). But freeze occured on 2.6 too.
- Game is somewhat heavily modified — content from steam workshop, "safe" save file editing
- Game start is "Young Gun"
- Steps to repro: load save, wait 10 seconds, catch the freeze. Fun fact — game is not totally frozen, because sound remains normal, mouse cursor is moving. And even more — after twenty or so minutes game continues executing like normal.
- Possible relevant changes, that caused problem — can't think of, unfortunately
- There is no crashdump, because game is not crashing. And screenshots are irrelevant.
