I have this young couple who started out in a trailer with their Doberman, Conan. They got great careers, made a load of money and so I moved them all into a shmancy house on the beach. Of course, it wouldn't be shmancy enough if there weren't also a pool! So I built them a pool and used one of those lovely Lagoon pool overlays. At first I thought the built-in stairs (that come with the pool overlay) would work to get them out of the pool, so I didn't have a ladder. Then it became clear that the stairs were more decorative than anything, so I quickly plunked in a pool ladder when I realized the guy was going to be late for work. He just bobbed around, waving and hollering, and didn't even attempt to use the ladder. So I grabbed him by the head and hauled him out myself. (moveobjects cheat was on, obviously) He sank up to his neck in the front lawn and continued swimming. Now he swims everywhere! From the kitchen to the bathroom, all over the property, etc.

Later in dawned on me that I'd put the ladder in backwards (!!?) and that's why he wouldn't/couldn't use it. I don't think the pool overlay caused any problem because I've used them before and never had a problem. I think me using the cheat to get him out of there might have done it, but I don't even care. I just want him to knock it off! I wouldn't even mind so much if he didn't already have ten body points, but he does so all this swimming is kind of a waste.

This happened to me before when I made a swimmable pond and didn't have the land around the pond raised by a click, but that was ages ago and if I ever fixed it I don't remember how. What do I do?

Have you tried resetting him? Turn debug mode on ("boolProp testingcheatsenabled true") and then Shift + Click, and go through the Pie Menu until you find "Force Error." Click "Reset."

If that doesn't work, the last time I had this issue, I deleted the sim with moveobjects and reloaded the lot.

Put him back in the pool, have him climb out the normal way. That should fix him.

@Ovenhole, Yep I tried that. No luck!
@CrystalFlame360 - Okay, I'll give those a whirl!
Thanks for your responses. I always get the best help when I come to this site!
