SH2004: Several files could be the asset

Class: content, exit code 1.

An asset named without an extension matches more than one file: images/card with both images/card.png and images/card.txtimg there. The engine won't guess which is meant.

How to fix it. Name the file meant with its extension, or remove the others.

For example:

base/images/card: error[SH2004]: 2 files could be this image: base/images/card.png, base/images/card.txtimg; name the one meant with its extension
