I created and added six textures to the GrassPlatform Tilesets. I named them in sequential order beginning with GrassPlatform_TileSet_26. https://i.imgur.com/KSIU40J.png After dragging the updated Tileset into the existing Grass Platform in the Tile Palette, seven random pink tiles appeared. https://i.imgur.com/JqqV7sZ.png That afterward updated everything in the Scene. I'm at a loss here. https://i.imgur.com/xJlFgte.png Short of redoing each tile again, is there a quick way to fix this? Thanks for your help.
