The newest version of LittleTiles available through CurseForge for Minecraft 1.7.10 is v1.2. This version is dramatically inferior to later versions of the mod (i.e., > 1.5) to the point of being nearly unusable.
SOLUTION
Please upgrade to a more modern version of LittleTiles.
I've created an issue over on the LittleTiles issue tracker requesting a newer version be uploaded to CurseForge. Not much for us to do until they approve the request.
