Crash when using glue and tags on the same line

When writing a story like so:

```
=== hurry_home ===
We hurried home <> #tag1 #tag2
-> to_savile_row

=== to_savile_row ===
to Savile Row
```

I've noticed that the game stops responding and the only way to exit is by killing the process, there are no logs, it just gets completely frozen.

The workaround I've found for now is putting the tags like so:

```
=== hurry_home ===
We hurried home <>
-> to_savile_row

=== to_savile_row ===
to Savile Row #tag1 #tag2
```

I don't know if that's intended behaviour or not, but I'm writing this just in case it's not.

I discovered this issue while using the 1.2.1 version inside the ink-unity-integration plugin, but was told to also post the issue here. The original issue can be found here: inkle/ink-unity-integration#212
