the problem is, the game doesnt tell you what that condition is, unless you click the heart symbol and then mouse over little. in my case it tells me to open a portal for becca, which is completely impossible because there is zero way to do such a thing and no guidance either. not sure if this is because i have reached the limit of the update, in which case it should tell me anyway or because there is a design flaw of the game. It really should guide you, even in a simple way, but it doesn't and expects you to already know, which when your new to it can be a head banger.
