I found a hex map online and put it into my campaign. I sized it to fit (page size 47x36, image size 3228x2432) and then tried using the rule tool to measure it's height and width. When I try to measure it's width it hits 11000 m and breaks. The tool disappears, doesn't come back, and the zoom on the page also whacks out. In my console log I see the error: Uncaught TypeError: Cannot read property 'PathCoOrdX' of null at HT.Grid.GetHexDistance (app.js?1535730296:195) at Object.d20.engine.getDistanceInScale (app.js?1535730296:345) at S (app.js?1535730296:345) at E (app.js?1535730296:345) at app.js?1535730296:345 at Function.k.each.k.forEach (base.js?1530633291:6) at Object.d20.engine.drawMeasurements (app.js?1535730296:345) at Object.d20.engine.drawOverlaysTop (app.js?1535730296:344) at n.renderTop (app.js?1535730296:340) at d20.engine.renderLoop (app.js?1535730296:346) Full error log Video
