Hello vidanueva...thank you for posting your details. One of our admin member will update your details in the spread sheet.
About your timelines, I am sorry to say, but Buffalo VO is one of the slowest. Some of our friends from Buffalo VO who have applied in July / august are still waiting to hear from their VO. So it will be a while till your hear from them. Now that you got your PER your file will be sent to your VO, and will be dealt with at the VO itself.
The next step as per process is to get an AOR (ack of rcpt from VO)
MR & RPRF (medical request and req to pay landing fees)
PPR ( Passport request)
Then VISA stamping.
About your address dissappearance, there is nothing much to read into that. Your address will keep appearing and dissappearing many times during the processing of your file.
As for your ECAS status - that is the first status update for everybody. As your file goes through step by step, your ECAS status update will keep changing. However exp has shown that we get to hear from the VO much sooner than the ECAS status is udpdated. E.g. I got my MR, and my ECAS still reads the first update.
Trust this info helps.
Cheers
