FxFoliageReplicator: array index out of bounds

Let's see on this code (engine/game/fx/fxFoliageReplicator.cc, line 1398):

-----------------------------------------------
// Yes, so calculate Global Sway Offset.
SwayOffsetX = mFieldData.mSwayMagnitudeSide * mCosTable[(U32)mGlobalSwayPhase];
SwayOffsetY = mFieldData.mSwayMagnitudeFront * mSinTable[(U32)mGlobalSwayPhase];

// Animate Global Sway Phase (Modulus).
mGlobalSwayPhase = mGlobalSwayPhase + (mGlobalSwayTimeRatio * ElapsedTime);
if (mGlobalSwayPhase >= 720.0f) mGlobalSwayPhase -= 720.0f;
-----------------------------------------------

This logic causes array index out of bounds:

mSinTable[(U32)mGlobalSwayPhase]
if (mGlobalSwayPhase >= 720.0f) mGlobalSwayPhase -= 720.0f;

because before "if (mGlobalSwayPhase >= 720.0f)" mGlobalSwayPhase may be more then 1440.0, so after "mGlobalSwayPhase -= 720.0f;" it may be more then 720, so using it in "mSinTable[(U32)mGlobalSwayPhase]" brings the error. So, sometimes foliages render incorrectly, somtimes a game crashes.

P.S. There are some similar code blocks in fxFoliageReplicator.cc which can cause array index out of bounds.
