I will chime in to say that I’ve also had plenty of this 412/RSOD problem (and I’m relying on equal measures of manual saves and autosaves; win10, FF56, TW5.1.14)...
1. White box stating ”Error while saving: XMLHttpRequest error code: 412” 2. The big, red ”embarrasment” box stating ”TypeError: xhr is undefined” (3. In the TiddlyServer window the 412 code is given for the last PUT) 4. Generally no saving possible afterwards without reloading the tiddlywiki (thereby losing any changes since last successful save), but sometimes I’ve found that the problem ”goes away” by itself after me waiting a while, meaning that I can once again start saving normally without having to reload...
