The expection might be Double X movie stock which is an older emlusiton.

Don't worry; subbing technology has improved over the years and today's 5222 also uses modern subbing technology. It won't reticulate under the kind of conditions we're discussing here.

I attempted to take an image but no matter how low res I use I cannot post it.

Resize it to 1000 pixels on the long dimension, and save it as a jpeg with lower than 100 quality.

And even if it would, just let the film in a single developing tank of water warm up closer to the wash temperature before you start the wash proper.
It is the rapid changes in temperature that are most concerning.
