I think everybody is affected by that reputation bug, didn't have time to look into it, just realized that I myself have the same 25 rep number :)
As for the API changes they were announced a couple of months ago, and its part of the new migration towards a cleaner API. Since not all the nodes updated to the new API there is a bit of confusion about that, but I expect it to be solved during the next few days.
Bots not voting is most likely related to nodes not being upgraded. SteemVoter announced that it may take up to 1 week until they redeploy their infrastructure, so we may be in it for quite some time.
