Hello again.
Sorry for the late reply but I had other things to focus on.
Anyway, the other day I decided to check for some gameplay videos of this mod and I did (of course) find some on Youtube. The y-tuber was very annoying but most of them seems to be like that (WHY?!) so I did try not to focus on that. the video did show some very good features (at least for playing a sim owned restaurant) so I thought it could be a good idea for NPC owned restaurants too. So I downloaded and installed it in my most updated install (being a non Patreon I had to stick to the free 3.1 version). In game play I did let a family visit a restaurant and it feel like the mod did some "magic" in game. The waiter did focus on my sims and were very effective serving the food and removing the empty plates and glasses. So I thought I was looking at a complete success...
But!...
...Then I did discover that my sims no longer could interact with sims outside their own family. They could greet people knocking at their door but not talk to anyone on the street because every time I tried they throw a routing problem and the action cancelled with the "walk by sim" claiming they needed to leave. I did send a sim to a nearby park but it was not possible for her to talk to other sims there either. And this is a big issue...
...So I did remove the mod and launched the game again. Now my sims could talk to other sims again so it must have been a bug. This can be a result of the mod clashing with something else or being incompatible with my game so I do not blame Carl, the mod maker for this things. But if you have any experience with this, please leave a comment. I did delete the mod from my mods folder but I did keep the log file in case someone want's to see it (off topic or in an other thread).
