Transplant list question

Hii my dad was diagnosed with NAFLD and was recently placed on the transplant list. On Monday he got the call for a potential liver and was told to come to the hospital by 10PM and surgery would be at 7AM. My dad and I got to the hospital at 10PM, went through the admission process and waited anxiously the whole night. At 4AM, we were told that the liver was not viable anymore and they could not safely perform the transplant surgery so they sent us home. Does this mean my dad is high on the transplant list? His Meld is 22. Previously we were told by his doctor he would most likely not get called for a liver until his meld was 25 or higher. Does anyone else have experience of getting called and then it not working out? When did you end up getting your new liver? What was your meld score at the time?
