What did you expect to happen?: I expected the trial to be loaded in the editor.
Can you reproduce the problem?: Try to load the trial
What did you do before the problem showed up?: I did 420 frames on the editor, yesterday. I deleted three or four frames and the last time I could open the trial was yesterday at 08:45 p.m

Finally, after 5 hours I managed to open an old save but no the one I did yesterday.

I asked for a copy of the trial JSON off-site.

What I found: The last CE's Co-Counsel frame (ID: 1780) was missing.
Attempted fix: Attempted to add a CEReturn frame consistent with other CC convos. This did not work as in editor there were other issues such as the CE being displayed at the top and having it's frames separated from the CE block.
Notes: Advised papaouté to delete and remake the CE which seems to have worked. No idea what caused this issue other than somehow the CE block was mangled during creation.

Hopefully this information helps whomever ends up looking into this deeper.
