That is a bug. Can you talk to Jahan?
Please email supportdos@larian.com, with a description of the problem and the report.zip file generated by the
D:OS support tool (for the PC version). The report will contain system info, etc, as well as your saved games. If file size is an issue you can delete older saves, or ones from other profiles, but a save before and after this problem occurred, at least, could help Larian track down the problem.
