I was just concluding from general rules and discussion after that Algerian mishap. I never had bases in breaking-up countries, so I canīt tell you explicitly the way it will be handled now.
But general rule is no base in another sovereign country except EU contract states after 97 or so. Since breaking up of SU and Yugoslavia leaves the world with a good number of new, sovereign states , it is perfectly clear that everyone will lose itīs bases outside his own, remaining HQ territory. I think I remember Sami promised to soften this process by giving out warnings.
