edit: I found Michael on roll20 and sent a PM The one that uses the API and the one that doesn't are both broken. There is a issue tracking link for the API sheet here . I've attempted to contact Casey Link (Ramblurr) before but with no luck. The main issue is that the image links are broken and nobody knows where GUMSHOE-Roll20.js is. There is no issue submission link for Authors: Michael Heilemann. Should these be taken down until they work properly? How do I contact these sheet authors? Michaels sheet works ok at first but has major issues when you re-launch your campaign. See screen shot:
