I am new to World Editor, I keep learning. I was trying to add some signs to the Pikes Peak map and it was OK, I saved the level. Then I came back to this map to drive again and surprise, the main ground texture was missing, showing a pink surface on the mountains with the "NO metrial" sign. I understood this was because of my edition. I removed it and the map worked fine again.I guess this is because this map is too old (released in 2020) for an earlier version, can you confirm this? If there is a possible workaround, I would be glad to know Thanks.
