Seems there's an issue with the Travis integration in the newest PRs. Travis still picks up the commits and run builds, but it's not visible inline in the PRs :(
Examples: #349, #350, #351, #353
Compared to: #313, #334 which has Travis checks inline.
I can contact Travis about the issue, but I'll like to know the Travis webhook status from our perspective first, but I dont have sufficient repo access. Could some of the repo owners please check Settings -> Webhooks & Services?
