Bug with painting

I had been having my sim paint on the sketch pad tablet thing and I wanted a specific painting so was making them do the same type of painting over and over again but they kept making the same one each time I tried moving to an easel but the same painting came up (8 times) I then swapped to a different painting type and they made the same one twice I then shut the game presuming it was a glitch and would be better when I reopened to game and it was my sim could make different paintings 

I had been making them paint repeatedly for about 3 actual human hours because I was trying to create a gallery wall so I’m not sure if they perhaps got stuck but it did fix itself when I reopened the game

I wasn’t sure if I needed to report it because I did manage to fix it but thought I might as well bring it to your attention 

thank you
