Hi I have a character sheet I have created that has some select elements with optgroups elements logically grouping option elements If I run a campaign on the live server with this sheet, the optgroups are rendered as expected If I run a sandbox campaign with this sheet, the optgroups are NOT rendered, and if I inspect the HTML with the debug console, there are no optgroups, it looks like they have been removed from the DOM -- yet the option elements they encapsulate are present, resulting in a select with a bunch of option elements and no logical separation between them I have tried with Chrome & Firefox, they both show the same problem : no optgroup's in a sandbox campaign... Is this a known bug ?
