Thanks for your help@VampiresTeeth. As @crinrict suggested, you can upload a .rar or .zip archive of the save file to a 1-click hosting service (like dropbox) and send me the link by PM and I'll take care of the rest. Cheers.
Quick update: QA managed to reproduce the issue thanks to your information @VampiresTeeth. The next step will be for the studio to find out what's gone wrong and to fix the bug. Cannot predict when it will be fixed but keep an eye on the patch-notes in the upcoming months. Thanks for helping with the investigation!
