*check_achievements breaks error logging in CSIDE

The \*check_achievements command stops the CS printLoop, sets some temps based on earned achivements, and then re-executes the current scene.

This seems to break CSIDE's ability to log errors, for e.g.:

**startup.txt**
```*title error
*check_achievements
*i_fail_silently
*finish
```

**startup.txt**
```*title error
*i_correctly_throw_an_error
*finish
```
