Remove cache from atlasJSONHash

[fitness23]

I have a game on mobile which gets slower and slower as you progress which I have identified down to the cache not being emptied. I have successfully loaded in a number of pngs and json files by using the following in a loop through JSON:

this.game.load.atlasJSONHash(theID, "image.png", "data.json");

Then I am successful in removing the sprite from the scene using the following:

item.destroy();

However when I try to then remove the png and json atlas json files from the cache, it errors, any ideas? I am using the following:

this.game.cache.removeTextureAtlas(theID);

Any help would be greatly appreciated I have successfully removed sounds and images, but not atlas.

The error I keep getting in the console is:

 

Uncaught TypeError: Cannot convert undefined or null to object
