vosk-model-small-en-us-0.15 has no exp/chain/tdnn/lgraph

I compiled the graph with new words in the `extras.txt` and `extras.dic`. No errors. Ran `decode.sh`, no errors. But when I look for the `exp/chain/tdnn/lgraph` to update the models it doesn't exist. The only path available is `exp/tdnn/graph`

Was the small model's directory structure changed or did something not compile correctly?
