give players the worldedit.light.fix permission node on the creative server FAWE always has lighting update problem when blocks are changed. Usually this is quickly fixed by placing down a block, but other times you get stuck with this... Spoiler By having the node added, players will be able to do //fixlighting and the problem will be solved
Be down for that as long as it doesnt create issues- constantly fixing shadow glitches when im cutting and pasting
