Some of my kids do not get picked up from daycare. I get a Scripterror on the parent and then the Daycare Hover-Over window does not appear on the kid anymore, but they also don't go home.

Chain of course needs to be the one to examine the log an answer. Even if it's not much help, just wanted to toss in that I get these errors frequently on inactive provided day care and did so back on GoHere v43 as well. The kids still get picked up (by being transported home) in those instances though, but the errors persist sometimes for sims days in a row until I finally shut the daycare down and try again in a few sim days.

Will sort that one in the next version.
