My sims have been having martial art skills problems.
In China, someone interrupted him right as he gained a skill level, so he never got a new belt. Even though he is a level 5 martial artist, he is practicing with the level 4 belt. Also, for some reason, I cannot ask my other Sim to spar with him. I thought it might fix itself when they went up another skill level, but that doesn't seem to be the case.
Today, my second Sim who wasn't having problems got interrupted right after gaining a skill level and he didn't get a new belt. He just went up again and once more, no new belt.
Is there something I should do to correct this? Should I put them back down to the skill level that matches their belt and raise them up again?
