Problem: Contracts are not being completed by the satisfaction of their requirements
Mods installed:
Quite a lot, though I suspect the only relevant ones are:
Contract config,
RSS,
RP0,
RO,
KER
Reproduction steps:
Have a contract requiring certain orbital parameters, thus far the only recurring problem has been with altitude, though it appears to have problems with inclination, period and eccentricity as well.
Put a craft into an orbit that satisfies the conditions
Cry as your hard work is for naught and you get no money.

(This also occurred to me on a manned suborbital flight where the condition was to fly over 260,000m alt, did just so and failed to reward me).
