My sims body disappeared [Solved]

[iJoeyMonster]

Hi~ So last night I was playing my game and something weird happened. I clicked the option for my sims to woohoo, and the one I'd clicked it for changed his clothes as he got ready to relax in the bed and his body disappeared. I've tried to reset him and it doesn't work.

Now, my came has frozen on me twice last night, so I started saving as much as I could and whenever something important happened. So I've saved a few times since that happened.

Here is a screenshot of what the sim looks like: http://prntscr.com/45sunm

He has his feet, head, and hands and some piece of accessory? (He doesn't have a watch so it's probably his shirt).

How can I fix this? Do I have to start over?

I really don't want to start over. I remodeled the house and my sim's boyfriend just got a promotion and my sim just got the news he was pregnant. I don't want to lose that progress, but I guess it's something I can get back quickly if I need to.

Is there a way to recover my sim's body?
I'm unable to get to the option Change Appearance upon clicking the mirror.


Edit:
I have a Windows 8.1. It was updated months ago, so that's not the issue and neither is my driver. My game was working totally fine before this.
Earlier yesterday before playing these two sims I'd downloaded the new patch from an off-menu source, as it wasn't letting me download it in the game menu.

 
Solution: Because there are no male maternity clothes, the sims body disappears. Once the male has the baby, you simply have to have them change and it'll go back to normal.

Have you tried to reset him?  Are you using a mod to allow his pregnancy or is it an alien pregnancy. If you are using a mod, it could be a conflict with him needing pregnancy clothing, but I don't use mods so I'm just guessing on that one.

It's a mod. It could be he needs pregnancy clothing, but he literally just got the news and he doesn't look fat yet.

Do I have to wait until he gives birth for him to go back to normal?

If that's why his clothes have dissappeared, it may well come back after he gives birth. Try making him wear just a pair of shorts.. not sure if that would do anything, but worth a try.

No it doesn't. He was just wearing undies when it happened. If it doesn't fix itself once he gives birth I may have to restart my family.

Aside from the mod for male pregnancy, do you have any third party content?  If you've downloaded clothing from a third party, it could be bugged and not showing up.

It was because he was pregnant. It happened to both of them and when they gave birth, I simply had to have them change and they went back to normal.
