Getting an assertion failure when the last number in this statement is a float/double, but not if it's an int (the only difference is the period after the ‘2’).

m_NewGhostOffset is an int
lastLoadedGhostRaceTime is a uint
Math::Clamp(x, min, max) is an overloaded function that takes either all ints or all floats

fails:
m_NewGhostOffset = Math::Clamp(m_NewGhostOffset, 0, lastLoadedGhostRaceTime == 0 ? 9999999 : lastLoadedGhostRaceTime * 2.);

works:
m_NewGhostOffset = Math::Clamp(m_NewGhostOffset, 0, lastLoadedGhostRaceTime == 0 ? 9999999 : lastLoadedGhostRaceTime * 2);
