I dont know if other people have encountered this but it seems that all my blocks have just disappeared even if its visible. But the blocks are able to be moved but unable to be seen by the viewer or anyone else can some one help?

I was the same. It's like you can insert a block but its texture is not displayed. The log only said that the model was not found. Can anyone help?
