I have encountered this bug also in writing or updating my articles.

Seconding this. Some friends of mine are trying to updateTales of the Valiant Character Sheets but it rarely saves where we want it to. On my own, I've noticed the following:

• I type details into two adjacent fields, in my case 'Allies and Relations' and 'Motivations'. I hit 'Save', and neither Updates with what I've written and instead shows up Blank
• I type it all again, this time copying it to Clipboard and a notepad. Does not save.
• Copy from said notepad, paste in, manually type the 'Motivations'. It saves, but the text I type in 'Motivations' has suddenly migrated to the field above, 'Allies and Relationships', while the original text there was not saved whatsoever.
• Tried Logging Out and Logging Back in, no change to the tesults.
• I tried clearing Browser Cache, no change to the results.
• I removed all Special Characters and used clean text without punctuation or parentheses, no change to the results, and if anything the data gained extra Slashes at the end of each line that I definitely did not type.
• I type it all out manually, wait a whole twenty minutes for the Autosave to register, but get no indication in the bottom-left corner that it has saved. Hit the Save button, it still does not Save.

Consistently this issue has occurred for all of us, across US East and UK, across multiple browsers (Firefox, Microsoft Edge, Vivaldi) and despite numerous refreshes and cache clearings. Frankly it's been very disruptive.
