Is this a glitch involving the freelance career?

I had my sim quit her job, she was an artist in the freelance career. What was going on was she was to paint (on the pad) something she thought the client would like. But when it came to talk to the client, the action would just drop immediately, and no matter how many times I would try, it would just drop. I even canceled the job, and attempted to do it again, but the action was the same. Is that a glitch, or is there something else going one that I just didn't figure out? I am willing to have my sim try this career again, if I can figure out what is going on. Before any ask, I am not playing with any mods or cc, and haven't for a while.
