The editor has a lot of problems for me (i am using chrome). 1) 70% of the time the editor does not load properly and i only see line numbers and a blank field, gladly I am able to toggle a line number and get it to load, so this is less the problem because I have a workaround. 2) This is even more annoying as I haven't found solution yet: Very often the preview stays blank, a dozen reloads, some time, less patience and any changes like deleting and readding a space in the html section later I am able to get it to load again. There is no html output for those cases, it justs stays blank and the DOM says there is nothing inside the sheet. All i get is <div id="root" class="charsheet></div> Did someone else experience such troubles? Edit: Ok the following IS indeed absolutely broken for me. The preview simply does not give a **** about my own css, but if I save it and relaunch the campaign I am able to see the changes in the actual charactersheets... The following is very likely not a bug, but I did not want to create another thread for it. Why can't even the simple code <div class="sheet-wrapper"> Test </div><!--charactersheet--> .sheet-wrapper{ border:1px solid red; } work? Even if i use .charsheet .sheet-wrapper{ border:1px solid red; } Nothing changes [edit: in the preview!!], the output is completly unaffected by my css - I mean this is the absolute basic test <a href="http://jsfiddle.net/0ujzj0ua/" rel="nofollow">http://jsfiddle.net/0ujzj0ua/</a> . Any insights/ideas? By the way, if i try to copy the html above into this text editor it drops the class="sheet-wrapper" oO Edit: I first did not post this under the bug report forum because I thought it was me being stupid and misusing css in any way and it turned out it is indeed a bug.
