To be honest, I have no idea what was wrong. I'm actually running an experiment right now to maybe determine the problem. I have some seedling started in the same soil I used to see if perhaps something was wrong with it. So far, I have one seedling developing it's second set of fan leaves and two more are emerging just out of the soil. So 3/4; trying different germination techniques as well. The first seedling looks good so far, but I guess I won't really know until it/they progress(es) a lot further. Also, I was wondering if adding a bit of a rooting hormone might help the seedling, so I might try with the last one if it sprouts. Honestly, I don't see why people don't experiment more, I learn the best through trial and error. Just grabbed a few random bag seeds and started a side project.
