Definitely a bug or some weird testing leftover, not sure where it came from, but I will take a note of this. At current working speed (less than 2-3 hours each week, sometimes not even that because no free time) it may take a while.
Though, shouldn't be an issue, because if the game can't find specified clothes name it technically shouldn't load anything...
Then again, it could as well throw an error or two, but after that if the game keeps throwing same error over and over, it's not showed anymore to the player (just ignored as it's the same error). Made it that way, because sometimes image can go missing or gets corrupted, so it simply isn't rendered anymore, but it's pointless to remind player of that after error been shown once or twice and game can still be playable.
