I want to upload a map pack but get an error saying "Only mod files containing AOE mod files accepted", when all that is contained in the mod are the .rms files and the png’s for the map thumbnails. Please help
Possible Solution: Make sure you don’t actually name the image “thumbnail.png” and include it in the mod directly. It prevents you from uploading the mod. (annoying bug.)
edit: Name it literally anything else besides that and it will upload just fine.
If that is not the issue then, maybe the folder/file format is/are incorrect? Sometimes things like this can prevent uploading mods as well.
