I know this isnt really the place to ask here but im a bit desperate. So i sent some XMR from my MyMonero wallet to Feather on tails. I didnt bother to check the adress and sent to the same adress i sent before.

But the money still hasnt come and after checking the addresses in Feather i cant find my old adress.

Do feather wallet adresses change randomly ? If so is my money gone forever ?

I appreciate all the help.
