My new BV/FT problem - vacations and walking

I recently got BV and FT, so now I have all expansions. I took all my previous hacks and mods out to test the gameplay this weekend, and everything worked great. But I wanted my hacks and mods back. So I came here to see the compatibility with FT and was happy to find the list in the hacks directory. I did not install everything, but the only thing not on the FT list I had running was the bvchildanimfix. I also have mods to replace default genetics and clothes, as well as a few catalog changing hacks (like "no stupid gorilla suit in CAS" and the like), the CEP, and globals for sectional sofas. I don't think those affect gameplay too much, but I thought I'm giving background here.
When I went back into playing, I had a problem with "Walk to lot" where the sims I sent go to where they are supposed to leave the lot, stand their, and then blank their queue. It was a child and an adult, and not the entire family, and I drove instead. Then, I went on a vacation. I've only sent sims on one vacation before, so I'm basing my experiences on that. After I booked it, it didn't ask e to assign/hire a housesitter (I have a baby and a dog), which it had done the first time I went on vacation. So the next morning, they were supposed to leave, but they wouldn't because the baby would be alone. It gave me a choice "Cancel" or "assign a babysitter", which didn't seem to do anything. It asked me twice, and afterwards canceled the vacation action on both sims that asked. So I had them call a nanny for "right now", and she came just as the shuttle left, without at least two of my sims. I don't remember any of them getting luggage and leaving. I thought it had cancelled my vacation, but then the vacation neighborhood loaded and all the correct sims were there. I thought it was odd, for sure, but at least they went.
Then, I wanted the sims to walk somewhere else. They all walked to the walking sign, then got the "arriving" action on their queue without leaving the lot. I tried to have them leave twice, but couldn't get them to walk anywhere (the group was and elder, two adults, and a child).
Then, after the vacation was over, and the house loaded, the sims were exactly where they were when they didn't get in the shuttle. They had the appropriate motives and memories, but never left a shuttle or "arrived", and again, no luggage. They didn't get vacation rewards; it didn't even ask me to chose any. They did get the hobby rewards pop-ups for after vacations.
The kid got in trouble for arriving to school late and the one adult for the same at work. I don't think this is a new problem, because the first vacation I went to they guy got in trouble for not going to work that day. Is the carpool/bus supposed to come for them on days they leave for vacation? I shudder to think what happens if they go to work and don't get in the shuttle.
I don't know if this is an EAxis problem, or it was a hack conflict problem. As I've said, I've only done two vacations, so maybe the vacations work inconsistantly. If their is a conflict, I think y'all are better equipted to figuere it out. All I have to look over their workings is common sense; i.e. if the hack is supposed to change the skilling on community lots, it shouldn't affect walking to other lots unless the game is accessing skill at that time. If you need more info, I'll be around. I'd like to have this resolved.
As you can tell, I'm pretty new to posting here, so I hope I'm in the right place.
Maybe the "I broke it" would be better, but I've seen this type of question here, too.
Thanks for everything,
Avi
