Does the issue occur in the editor or during gameplay?
During Gameplay.
If it's a gameplay issue, please specify which movement system and camera type you're using (free movement vs. grid movement, third-person vs. first-person) or N/A if not applicable:
N/A I suppose
Briefly describe the issue you're experiencing:
Changing players model during the dialog breaks the game. Player's replicas in a dialog are no longer shown. When the dialog is finished player can't move or interact.
Are there any errors in the in-game debug console or external console window?

Provide the steps necessary to reproduce the issue:
- Create a dialog with a script in the middle of it. Script has the following line: set_entity_model(player, "model");
- Run the game and start the dialog. Dialog will break after script execution. As well as moving and interaction.
There is a workaround. You can put the script at the end of a dialog and then run another dialog from the script.
