This screams cutting back on quality control to me. Same issue in three systems means your QA is not focussing resource onto making sure that system is not going to break again. Given Soyuz and Progress have 50 years of flights with relatively few incidents (Soyuz 56 years, Progress 44 years) they are pretty robust so likely could absorb some drop in production standards and quality assurance. But it seems they have cut the bone so fine they are producing the same fault and their teams are not testing enough for it.

The budget for that is now probably floating somewhere in the Black Sea with Rogozins name on it.

The fleet should be grounded for a serious investigation, but there is no way that is going to happen politically.
