+### Troubleshooting
+
+#### Missing model at startup
+
+The `separable_float` variant of the THA3 models was previously included in the *SillyTavern-extras* repository. However, this was recently (December 2023) changed to download these models from HuggingFace if necessary, so a local copy of the model is no longer provided.
+
+Therefore, if you updated your *SillyTavern-extras* installation from *git*, it is likely that *git* deleted your local copy of that particular model, leading to an error message like:
+
+```
+FileNotFoundError: Model file /home/xxx/SillyTavern-extras/talkinghead/tha3/models/separable_float/eyebrow_decomposer.pt not found, please check the path.
+```
+
+The solution is to remove (or rename) your `SillyTavern-extras/talkinghead/tha3/models` directory, and try again. If that directory does not exist, `talkinghead` will download the models at the first run.
+
+The models are shared between the live mode and the manual poser, so it doesn't matter which one you run first.
