Re: Vertical Challenge Rock Wall causes crash
@leverettken Please test the climbing wall in a new save. You don't have to spend much time on it; just load Sunset Valley, pick one of the rich households to play with, plunk down a climbing wall or two, and see whether the sims can use them. If it still doesn't work, try uninstalling and reinstalling the wall in the launcher.
If the wall works in the new save, the issue is likely something in your current save. It's worth testing with another sim, just in case your main sim is the problem; you don't need to save your progress afterwards. You can also try selling and rebuying the wall, or placing it somewhere else on the lot, preferably somewhere open with no other objects around.
