Certain skills will not turn gold
Sorry if this is a known issue, but I did a quick search and couldn't find anything about this.
My current highest lesson is "Travel".
A week or two ago, my "Occupations 2" skill went from gold to 4 strength bars. I tried to strengthen it, by doing the timed test, and it simply wouldn't turn gold and show that it was fully strengthened. I did the "strengthen" activity seven times in a row at one point, getting 19 or 20 points every time, and it still shows only 4 bars of strength.
Now, the same thing has happened with the skill "Sensations".
I assume this is some sort of bug, but is there maybe something that I'm missing?
