I'm pretty sure everything you mentioned is classified as "bugs w/ Elite". We have a pretty comprehensive list of issues here in the forums that contains many of the issues you mentioned.
As for the "deactivating" from a clan, that doesn't happen automatically. You either have to leave the clan or they have to kick you from the clan. You don't get auto-kicked after so much inactivity.
As fare as the rest of it, I don't think there is anything you can do to fix any of them aside from keep trying.
