Describe the bug
Ignoring the clear PyTK issues pre-issue happening; this happened to me twice as of now and only when I delete command that I could have possibly mis-spelt.

To Reproduce
Exact steps which reproduce the bug, if possible. For example:

1. Start SDV
2. Type in a command like player_add sdosjdo
3. Start backspacing it
4. Observe the automatic killing of SDV

That seems like an issue with the .NET terminal driver (or the terminal itself). Unfortunately I don't think SMAPI can do anything about it.
