skill strength bug ?
I don't know if this is a bug or somebody is tweaking the word strength algorithm.
One moment my skill has 4 bars. I come back minutes later the skill is golden now. (usually a different skill deteriorates at the same time)
Example: my German tree-> skill "Communication" (moments ago)
This happened several times already
edit: minor issue - whenever I post a discussion there aren't any flags, numbers or streak icon next to my username. They appear when I refresh the page
