Not exacrly but I was surprised last week when 2 segments opened at T-36 of the first one (ie at T-40 something of the second flight). This is how it worked in the far past, but hasnt worked for awhile.

However happy I was to be able to do OLCI only once for an AY ticket, it was all destroyed a few hours before take off. Suddenly I wasnt checked in for segment 2. ...?!? I went online and repeated check in.
At the airport my second BP was issued and it had BN1... So they are clearly tampering with this system too. The first OLCI worked halfways but some systems refuse to recognize it so a second OLCI is needed if the first is done at more than t-36 of the individual flight.

Funny how things that works perfectly suddenly gets "enhanced" and it takes months or uears of adjustments to get back to original state.
