And/or the wrong temps when they were blooming.

I normally grow at least 15 varieties of winter squash with no issues. But several years ago I tried a new-to-me variety with no success at all. I had planted about 20 seeds in an isolated location so I could save the seeds. The plants got big and wild but it was a hot summer and none of the baby squash set. There were pollinators there as 2 other species grown next to this 1 set fine. Then around Labor Day when it cooled down a bit, the squash set. But of course by that time it was way too late for them to mature. My conclusion was that variety just didn't like the really hot weather.
