Vertical Challenge Rock Wall causes crash

@leverettken  Please move your entire Sims 3 folder out of Documents\Electronic Arts and onto your desktop.  When you open the launcher, a clean folder will spawn with no content.  (Your saves and other content will be intact in the folder you've moved but temporarily not read by the game.)  Don't add any of your existing content to the new folder; just download a fresh copy of the climbing wall, install it, and let me know whether it works in a new save.

If it doesn't, I'll try messing around with it myself.  I own the wall but haven't installed it, but I can experiment a bit.  Please also let me know what kind of install you have: Windows and Origin/disc/Steam, or macOS 32-bit or 64-bit.
