Cannot add a cache to a New List

[+vpdj]

Trying to add a Geocache to a New List - keep getting "something went wrong"

Tried from the cache page as well as the filtered list

GC5E8QJ ▼  Excellent Adventure of the Zombie Horde #1

and

https://www.geocaching.com/play/search?ot=4&kw=excellent&nfb[0]=vpdj&r=21&f=2&o=2&cc=1

Using list name ExcelAdventure -- "Something went wrong. Try refreshing the page."  Refresh does not help.

I went to the cache page, GC5EQJ, and clicked on Add to List, created a New list with ExcelAdventure as the name, and got the expected "Saved!", and I now have a list with one cache...  I'm using Windows 10 on my laptop, Chrome browser.  Perhaps try a different browser?

I have tried different computers and different browsers - IE / Firefox and Chrome - still happening after over a week

Tried your search string (without &cc=1) and added all caches to a new BM list.

Think I have finally found the problem - I have hit a limitation on the number of LISTs that can be added to for my account - about 99 or 100 LISTs.

Once I have 99 or 100 lists, it will not allow me to add to a new list until I delete an old list.
