I could not reload and share a screen shot about 6 hours after 1331 expired -- or at least I think that was the puzzle number. it would not load anything from the server

We've seen that "the sequence position requested was greater than the number of residues in the pose" message before, but only in design puzzles where you can add or delete residues.

The puzzle id in the debug.txt, 2003287, matches the 1326 puzzle page, https://fold.it/portal/node/2003287

Hard to understand why there would be an extra segment in a de-novo.

Just in general, there are some issues with opening old puzzles:

You must have played (at least opened) the puzzle using the same client, or else the puzzle won't be in the list. If the client is connected to chat, you can try downloading the puzzle using the "Need this puzzle? Download it to your Foldit here" link found on each puzzle page just above the comments.

Sometimes even puzzles which you've 100% sure you've played won't appear in the list. Downloading the puzzle again may or may not solve the problem. This can happen even though all the necessary files seem to be there.

Sometimes old puzzles crash the client, as in this case, although you rarely get a debug.txt.

Even if you successfully open an old puzzle, previous solutions may not be available. During the Amazon Web Services cutover, only more recent solutions were kept on the server. But even locally saved solutions may fail to show up for some old puzzles, even when the files seem to be there.

In some cases, I suspect using an older client might solve the crashes, missing puzzles, and missing solutions, but I haven't tried it.

I don't have exact numbers, but it seems like somewhere around 10% of old (but not ancient) puzzles can't be opened for one reason or another.

On top of these issues, we're having server issues at the moment, although seem to mainly affect uploading to fold.it, not downloading.
