Getting clear information on this from the team at the moment is a bit of a mess. 
On one hand, getting informed that the PvP Teams for Citadel fights not being saved, is what was actually fixed and not *generally *all PvP teams. But then finding discussions where there was a fix for PvP Teams that had Immortals, not being saved, being fixed
Then, on the other hand, being told that only 1 team per Region is saved at the moment, which could be why it appears to save inconsistently (which was mentioned in the patch notes thread), or it currently isn’t saving any at all.
The intention is that each Region should be able to have a team saved, to match each restriction, once a team has been formed.
I’m currently reclarifying the whole issue with the team to make sure it is clear that this issue was not resolved.
