I'm still using LDL, so this may function slightly different for Explorer Mode. (It's not supposed to... but it might.) 1. First, check all your tokens, to make sure they are only set up to use one lighting system. I just found out a couple nights ago that several of my players weren't able to see explored areas of AFoW, because somehow their vision was turned on in UDL. Everything else was correct (page settings only for LDL, token settings for LDL) but that prevented them from seeing explored areas. So definitely double check that each token is only using the system you want, and that the page is set up to only use one system as well. 2. Then on the Fog of War toolbar, click on the Reset Fog button. That should reset both the AFoW/Explorer Mode and the Fog of War/Darkness. 3. Next, select the Reveal Areas button on the Fog of War toolbar. 4. Last, hold down the Alt (PC) or Option (mac) key and drag over the entire map to remove only the Fog of War/Darkness. That should have reset all the hidden areas on the page, and removed the Fog of War/Darkness, leaving the explored areas hidden until tokens explore those areas. If you don't want to use Fog of War/Darkness at all, you have to turn it off on the Legacy Dynamic Lighting tab of the page settings. It's weird that it's on it's still on that tab, but it functions for both LDL and UDL. I'd strongly suggest using a Dummy Account to get a true player's view and use that for testing, instead of using 'rejoin as player'. Then it's an easy task of making sure the 'dummy player' is on whichever map you want to look at, at the same time as you are making changes, instead of having to jump back and forth.
