Do you think it's because I use Boolprop sometimes?

Whenever the hour is up (at :59), the error pops up. It's been happening for so long, it's very annoying. I think it has something to do with an 'age controller'. So, can you help me?

Edit: Sorry, file uploaded! I didn't know which one to upload because there are like, five, to ten friggin' text files ;; I was confused but I just picked whatever. They're all basically the same.

Edit2: I have no hacks of TwoJeff's, or Inge's. I recently downloaded some Simlogical stuff, but the errors were happening before that.
