Hi guys, I keep getting this error that reads:
Object Error
An error occured in object "Controller-Age #10,
Error: Bad gosub tree number.
The stack trace is saved in:

It happens like every few real minutes and it's annoying. It always happens at 5:59 in Sim Time and my sims won't age. I don't have the aging cheat on. Every time it's 6:00 nothing happens. This all started since I installed the Fun With Pets Collection, with Pets (duh) Family Fun and Mansion and Garden stuff. I haven't patched my game. Whenever this happens I choose Reset.
I have a screenshot.
So can someone tell me what the problem is? Do I need a patch or is it something else?

Try going through the Game Problem FAQ (doing each step, not just reading it).

And yes, you should always patch your game, though I haven't heard that aging difficulties are one of the things fixed in the patch. Just as a matter of principle - if the code was broken so badly the company actually budgeted time to fix it, it must need fixing pretty badly.

Thank you for the help, but I haven't gotten any other patches and I tried to download the Pets patch and it keeps giving me this error that Pets isn't installed, when I do have it.

Have you done the Game_Help:Game_Problem^wiki FAQ yet? You were supposed to do it before posting. We're still waiting for you to complete it and tell us what you did and the results of each test.

Was your Pets EP included in a collection pack? The collection packs don't usually require patches.
