Hey all, I had a complete game failure last night due to two issues: Dynamic Lighting and API. I explain the issue below but thought it useful to explain my setup first. The DL issue was the real problem. I mentioned the API issue (now seemingly resolved) in case there is any connection. Setup: I have recently added the Sunless Citadel Add-On (from Tales of the Yawning Portal). For DL, the page settings were: Line of Sight, Update on Drop and Restrict Movement On. Global Illumination On for Page 1 Off for Page 2. Fog of War Off. Each player "Has Sight" Off initially. For API I had the Group Initiative and Torch scripts running. (Bonus Side Question: Why would you use Fog of War if you are using DL? DL seems to render FoW redundant? DL Issue: So on Page 1 (Fortress Top), Players 1 and 2 could see nothing (correctly as Has Sight was off). Player 3, however, could see everything, including stuff outside the dynamic light area, (because Global Illumination was On). I double-checked and Has Sight was Off. I turned it on and set the light source but this made no difference. This was not a major issue on this page (except it made me nervous about moving Player 3 to Page 2, (Fortress Bottom). I turned Has Sight on for the other Players and they could see what they should see. Things got really odd when I moved the players to Page 2. Players 1 and 2 again could see what they were supposed to see (nothing initially and then the landing room when I gave them a light source). Player 3, however, could now see nothing. I checked again and Has Sight was on. I set them to Emit Light. I also set so it so that light was visible to all players. I checked the Player had control of the Token. All fine. Moreover, Player 3 could move their token around the room (but not further) and their light source moved with them (and visibly changed for the other players). Further still, when I opted to view from Player 3's perspective (Cntrl L) I could see what they were supposed to see. Throughout, they could only see Black. I've found no solution. API Issue: The Group Initiative and Torch commands (and associated Macros) suddenly stopped working (they had worked fine earlier in the day). I checked they were set up ok, and it said they were. However, I checked back this morning, and there was a message saying the API Scripts had been shut down as there was an infinite loop. I restarted the Sandbox and all now working fine. I'm a Noob at running Roll20 (previously just used it as a dice roller). This was my first proper game using the VTT and it was an epic fail. Any help would be greatly appreciated. Thanks for reading.
