I created a map with final alert. I put the file "carte de ouf.map" in the directory "maps". The map displays correctly in the discussion room before launching the game, but then the game never launches, I have a black screen. I've made a short video here : https://www.loom.com/share/ec56fb876197411ba3f9eb0dd4b3f713 If someone can help...Thanks a lot anyway!
