I paid 750k for the playful infection yesterday morning 2/18/18, said I'd be notified, and as of this morning I still have nothing. Is there something I'm doing wrong? Does it take longer than a day for the virus to start?

If you don't get bitten by other users with this infection, it can take a long long time for the virus to progress... You can go to this topic (https://subeta.net/forums.php/read/885133/Biting-Directory-Come-to-Bite-or-Get-Bitten-), ping the people that have your strain to bite you and then it shouldn't take long for you to get infected :)

I have that strain so I'll keep biting until you're infected.

[edit]All done, enjoy!

Thanks everyone! I appreciate the help! And the bites!!! Yay :)
