Usually Renpy attaches a lot of useful information in their crash reports, so unless we can get a proper crash report, it will be pretty hard to do anything.
Also GOM? Is that a Linux thing? A crash report would have told me your operation system, where in the program the error occurred fr koom and what type of issue caused the crash, all stuff that would have allowed us to probably rather quickly have solved your issue. So I am sorry, but until I get a lot more specific information, neither of us on the Wifetrainer team will be able to help you.
