A user reported that he got an edit conflict with themself. The difference between the two "revisions" shown in the edit conflict were that one had his signature expanded while the other hadn't.
Here are the two versions of the paragraph:
:::::I just noticed something else: For the previous SMILES, if I remove the H2 from the oxygen atom for each of the water molecules (The H2 is unnecessary because the oxygen atom in each water molecule has a formal charge of +1.), [https://chemapps.stolaf.edu/jmol/jmol.php?model=%5BCr-%5D1234(%5BO+%5D)=%5BCr-%5D(%5BO+%5D)(O%5BC-%5D(C)O1)(O%5BC-%5D(C)O2)(O%5BC-%5D(C)O3)(O%5BC-%5D(C)O4) the oxygen atoms in the acetates align for the two chromium atoms].

The users had the beta-feature Two Column Edit Conflict View enabled but we think that this is not a bug in this extension bug in Core.
