Update in the last 48 hours?

[Nickel AP]

Was there an update at all between 1-17-17 and 1-19-17? I had been repeatedly doing kerbin orbit tourist contracts and could continually complete them, first try, at least 5 times in a row. Today I attempted to do a kerbin orbit tourist contract with the exact same ship and could not achieve 70k ap-70k pap orbit. I tried multiple times and ran out of fuel every time BEFORE hitting orbit, not even enough fuel to de orbit. whats going on?

Additional info: Was using reliant initial stage, terrier second stage. In an attempt to be extremely cost efficient I was using just enough fuel tanks to achieve orbit and de orbit. With consecutive failures today I tried switching over to thud x2 on initial stage for greater ISP at sea level to no avail.

In all humility it may be my flying but I was pretty consistent at hitting orbit with this same ship. I don't know what could have changed in my flying style to restrict me from hitting orbit.

There was no update at the times you've mentioned about (from all I know). No bugfix, no major one.

If you don't do a gravity turn and instead go directly up, there is an extremely huge chance that even a small change in your flying style can negatively effect your fuel usage.

Personal Note: Being extremely cost efficient can cause even small mistakes to drain all your fuel. I know since I had the same problems during the days I didn't know how to gravity turn.
