Ziechael said: No joy, refreshed my game, have restarted the API each time to make sure no silent crash is happening and have renamed the tracks to add the -players- suffix but still getting the crash, it sends the powercard prior to the crash however, it's just the sound triggers that seem to be crashing the API :( It works for me, ver 3.3.0 (PowerCards) and 1.04 (Roll20AM) without any modifications to Roll20AM. Just tried it with a fresh one-click install.
