Eidolon ran off early

[Kahrain]

So... just had this happen twice. Even though the bounty board in Cetus says there's more than 10 minutes left (I think it was 20 and 16 when I did it), the teralyst eidolon decided he didn't want to play and took off shortly after starting the bounty. In the first one, Onko came up to say that the sun was rising right before the eidolon ran off.

I was using a Harrow, Lanka, Mara Detron, and Glaive Prime, I don't know what the other people in the parties had. Don't know if it makes a difference, but noting it anyways.

Eidolon sees us amazing Tenno and just runs. HA! (i'm crying inside)
