In FirstMission.php, strange behaviour when a function does not end with wait_for_action

[david blanchard]

In FirstMission.php, I comment the line 102, which is the last line of home_hacked() :
$this->wait_for_action(REPLY, 'getting_an_isp_website');

Then I run the mission, I successfully hack my home page, until I get the following in the chat : 'That was the easy part, though. Ready for more?'

The mission should stop here. But if I perform another action, like reaching another web page, the content of the chat that corresponds to the successful hack disappears and is replaced with the one of hack failed ([...] try again - you're getting there.).
