Reviewer's Guide by Sourcery

This PR fixes a bug where custom roles were not being saved during custom chapter creation. The fix involves saving the custom roles to the obj_creation.custom_roles variable and then updating the global.chapter_creation_object with the saved roles. Additionally, the custom_roles variable is initialized as an empty struct in the scr_chapter_random script.
