We've mostly been spared from frozen BGS. Even when our expansion state froze after the PP 2.0 patch, we didn't mind because we had more than enough systems already. However now my colonized system has been stuck on pending election for 5 days now. It's annoying because I don't want to make futher constructions or chain more colonies from there before our faction controls that enclave. Maybe I should build a settlement so see if that unfreezes it.
