Right Side Preview not working after loading a .ink file

**What Version:**
- Inky win32-x64
- Inky version: 0.12.0
- ink version: 1.0
- inkjs version: 1.10.2

**What OS:**
Windows 10 (at least one major update behind, I am afraid)

**What happens:**
When you save a project and load it again later, the preview section does not work as expected any more.

If the .ink file is small (like, saving the new project preview ink), the preview might appear, but the loading icon keeps loading. It does look like it will work, but once you hit the END/DONE, you cannot rewind properly. Currently it only shows "Once upon a time..." without any choices.

If the .ink file is big (like the one I made yesterday night), the loading icon keeps loading, but no preview appears after all.

In both cases, the actual source code is available totally without anything missing.

**Steps to reproduce:**

1. Create a new project with some text in it (the preview is sufficient in my case)
2. Save it as an .ink file somewhere (in my case, its located in my user folder Documents)
3. close Inky, reopen it
4. load (either select or select recent) the saved project
5. try to start the ink (if there is any text after all at the right)

**Workarounds:**
Well, you can create a new ink projekt and copy all you source code inside this ons. That will work. But once you saved it, it will happen again when you load it

**Thoughts:**
Oh dear, what a bug. I am a bit astonished that this slipped by D:
