Dynamic lighting - Walls stopped blocking vision

I was playing a game last night and we noticed that the players could see the whole map.  The walls were still in place on the light layer, but were not blocking light and in some cases were not blocking movement.  This was the same for all players so we deduced is wasn't a local browser issue.  We managed to carry on and complete the session with the players ignoring anything they might see by mistake.    This has been working correctly for many sessions.  I have since checked the lighting settings and they had not changed.  If I delete one of the existing walls and replace it, the new work works fine.  I plan to replace the walls, annoying but not a major task, but I would like to understand what happened so I can avoid it happening again. Has anyone else seen something like this? The last session that this all worked was: 13th August 2026 The session were this was not working was: 19th August 2026

Same here, a fix been deployed during the night (10hours ago ~) but it doesn't seem to have fixed the issues :(  Hope that it can be fixed soon.

More info on this bug Plus this : Thank you so much for your patience. We know this has affected a lot of people in their games tonight so we appreciate all the reports. Devs located the issue with a recent issue that unveiled another issue (big ol’ domino effect, unfortunately). Only users who had their pages open during this time are affected by this. You may find that in some cases your drawings (including Dynamic Lighting lines) would have moved to the top left corner of your map, affecting player sight. The next step is to institute a rollback, which is usually only available for Pro + Elite accounts. However, we are making the rollback feature available temporarily to allow this for all users affected, even free accounts. You can read the  steps and FAQs here  (we recommend reading the whole article!) If you’re struggling with the rollback or run into any challenges with it, then please  contact us through our Help Center  and our Customer Service will help you!

Thanks for the responses

Rolling back make it work, thanks !

Thanks for the suggestion.  I only had a few fairly uncomplicated maps, so I deleted the walls and re-did them.   The game seems back to normal now.
