I'm trying to hack in a few changes for a homebrewed FAGE game I'll be running soon. I (perhaps foolishly) hacked the base AGE system sheet to my liking and then obviously it doesn't work when I try and bring it into a custom game because the age system sheet.json does a fair load of things (primarlly setting what age game type your using and changing the content of the page acordingly). I was thinking I'd just be able to setAttrs all the attributes controled by the sheet.json on sheet:opened and that'd be that but it doesn't seem to be working like I thought it would. In the UI it's almost like it's not even loading the css at all. I can see in the browser dev tools that it's getting the attributes I'm setting but the sheet is still showing the unstyled version you'd get if you didn't have a sheet.json. Anyone got any ideas what I might be doing wrong/if i can even do what I'm trying to do?
