Bug in explosion.cc

I have a demo I've been working on for a while, and it has lots of explosions. I noticed that I'd get weird crashes when I had many enemies and lots of explosions (like, dozens of enemies, hundreds of explosions). I traced it back to game/fx/explosion.cc and processTick(). The corrected code is below.

//--------------------------------------------------------------------------
void Explosion::processTick(const Move*)
{
   mCurrMS += TickMs;

   if( mCurrMS >= mEndingMS )
   {
      deleteObject();
      // I added this return.  Otherwise it's going to delete the object but then call explode() on it
      return;
   }

   if( (mCurrMS > mDelayMS) && !mActive )
      explode();
}

This made my segfaults go away. Does this seem right to you guys?
