Your issue appears to be the Work of the Non-Awesome, as something is modifying a global BCON which the new BV BHAV code expects to be present, causing an error.
Damn. I was afraid of that. I'll have to check to see what I added in the last day or so, as I was playing fine yesterday.
If your sims are stuck on a vacation lot because some have been accidentally deleted, you can resummon them, shiftclick, and remake selectable again using an Ingelogical shrub. This should fix the lost sims. The code "boolProp dormSpecificToolsDisabled" will reenable buy/build and enable you to install an Ingelogical shrub if you happen to be lacking one.
Well, as noted above, I did try exactly that. It enabled me to get them checked out of the hotel and out of the vacation hood, but the home lot was not playable when I arrived, and the game was stuck to the point that I couldn't exit normally. I was just wondering if there was a better way.
