I have the same issue with API crashes - seems to be with trackerjacker. Before the most recent set of Roll20 and Shaped sheet updates over the last few weeks, all I'd have to do to get the scripts working was disable and re-enable TJ. That doesn't help any longer. It'll load in for a bit, but then everything will stop working. Haven't been able to link it to anything specific that I'm doing in-game. No errors appear in the output console - it'll either load only one script, or no scripts at all. I'm running TJ, bloodied and dead, torch, isGM, groupinitiative, visualalert, aureahealth, blood and honor, a random herbalism script, and a sound fx script in my D&D game. In Shadowrun, I'm running TJ, isGM, visualalert, aurahealth, the same sound fx control script, and blood and honor.
