Yes, I figured it was the safe mushroom based on that text, but did not have success with either.
While you are fixing the bug, there is another bug (unless there is a reason for it that I missed):
The list of dangers always includes the word 'small mountain' on the list, but without obeying the typical spacing rules (always no space, even if language typically has spaces).
Another more major bug, if you ever reload a save, then it remembers the vocabulary words but not the grammar. Spaces between morphemes disappear and the pluralization system changes.
(EDIT):I just remembered another bug - the text that is a tool catalog sometimes the text overlaps or is cut off in the top left if the words are longer. The word 'tool' can cover the words for the colors, which in turn can run off the page.
