So I made a PR for this sheet that has just been merged, and the style of the roll templates are no more applied, whether on a old game or a new game. I marginally edited the templates styles. They are compiled with stylus so a syntax error is unlikely. Here is an excerpt of the CSS where we can see that the selectors are properly prefixed by the template name. I just forgot to prefix one class that is used in the template. .sheet-rolltemplate-ironsworn_moves .sheet-roll-name { padding: 0.2em 1em 0.2em 1em; text-align: right; font-size: 13px; font-style: italic; } .sheet-rolltemplate-ironsworn_progress .sheet-progress-name { padding: 0.2em 1em 0.2em 1em; text-align: left; font-size: 13px; font-style: italic; } .sheet-rolltemplate-ironsworn_moves .sheet-roll-container, .sheet-rolltemplate-ironsworn_progress .sheet-roll-container { background: #33323c; color: #fff; font-size: 1em; font-family: 'Roboto', Arial, sans-serif; border: 1px solid #000; } .sheet-rolltemplate-ironsworn_moves .sheet-result-row, .sheet-rolltemplate-ironsworn_progress .sheet-result-row { display: flex; justify-content: space-between; } And using the inspector in-game I can see that no selector matches. Needless to say that the rolls don't look good at all now and a fix for this is quite urgent.
