Build crashes on build machine (-nographics option)

We've been getting crashes on our build machine recently when building our game:
```
build 19-Aug-2019 12:41:04 Updating ProjectSettings/ProjectSettings.asset - GUID: 00000000000000004000000000000000...

build 19-Aug-2019 12:41:04 Crash!!!
```
This seems to happen when we have the InkCompiler included in the project. When we remove the InkCompiler the problem disappears. We're using Unity 2019.1.8f1 with Ink 0.9.1

Let me know if I can share more logs or the crash dump to help resolve this. We don't want to remove the InkCopiler from the project just yet since it's useful for auto compiling.
This is the stack trace:

One thing that might be responsible, which I noticed just now when making a build locally, is a popup that prompts you to build outdated Ink files when making the build. Maybe this can have something to do with it (since we're using the -nographics -batchmode Unity switch on the build machine)
