Incorrect address on the application?

I provided my mailing address to my new sponsor and on my visa application. Now I am concerned that the Home Office will contact them to see if that is my home address. It is not. The reality is that I have no home address right now (ie technically homeless). I don't want them to contact the mailing address as they will not be able to verify I live there. (Proof of address was not one of the documents I had to provide on my T2 application document upload)

I previously had updated HMRC with that, but now I realize they are different things.

I am seriously stressed out that I have majorly messed up.

Any guidance is appreciated!!

it should not be a matter. My colleague used the office address in her application and got approved with no problem.
