The stadium was designed to have a closable roof and be air-conditioned/heated for year-round usage. However, the engineers screwed up the roof design and couldn't actually complete the part that opened and closed. This was after it was basically complete, so it wasn't really possible to go back and fix it. So, it became an open stadium and the plan to heat and cool it went out the window.

There were also problems with the field, it wasn't designed to handle significant rain and snow, so drainage was an issue. Since it was designed for indoor use it was set up with artificial turf, though toward the end of its life it switched to natural grass. Ultimately, the exposure to weather and just general age made it uneconomical to maintain, plus there just aren't that many touring events that it could attract given the much nicer new stadium a dozen miles away that was fully enclosed and air conditioned.
