Typescript Service Not Working with Version 2.6.2

When I upgrade my Typescript version from 2.5.3 to 2.6.2 (latest as of this posting), PhpStorm's Typescript service does not register code changes without restarting the service.

For example, if I have a Typescript error showing in the errors window, and then I change the line to remove the type error, the errors window does not update until I restart the Typescript service. This behavior is not the same as if I am using Typescript version 2.5.3. In that version, the service updates on file save.

Every time I make a change to any file in my project, this is the error that is thrown in the Typescript service console to indicate that the service failed to update:

```Process: Error processing message: Debug Failure. False expression. Error: Debug Failure. False expression.

I'm not sure what this means, but every time I make changes in a file I see this error message in the Typescript service console. As I said before, this does not happen when using Typescript version 2.5.3. Is anyone else running into this issue?
