Thanks. I never close my browser (it currently takes 22GB of RAM :p) so it makes sense, next time I'll use a dedicated browser. Well that's a given since I will use Tor. Since the data is destroyed on the server then using a new session with the same ID doesn't provide any "safety" regarding eventual problems, anyway.
yea I've had same issue and didn't notice and sent coins again to same deposit address and they fixed it for me.
I'm still waiting on this "different deposit address" issue/bug still though. Missing 0.3 bitcoin. Did determine the wallet I was originally given also belongs to them so hopefully its a quick fix.
