I've got Baby/Toddler bugs to report!!
The first one is a fun one. :D Seems like Toddlers that can walk can use the Pneumatic Elevator Tubes. Problem is, when they use it, they stretch to the YA rig while in the tub and then shrink back to Toddler when they exit. I don't think anyone has reported a mesh-stretching bug yet, so if I'm the first, yay!
I'd like to confirm the playpen bug where the abacus is unusable, but my walker works fine. My Toddler was able to learn how to walk and play on it, gaining both respective skills in the process. However, once my tot gained a skill point for... whatever skill you get for playing on the walker, he jump/reset out of the walker. My PlumBot, who was outside tending to the garden, was able to pick him up and put him back in, though. I'm not sure if this is a compatibility issue or a corrupt ccmerge.package. Is there any way to check?
On a related note, adult Sims who use the "Play with..." interaction on the playpen get stuck in a loop. I had my tot's Mom stuck using that interaction for several hours, not addressing any of her motive needs, until I manually canceled the action.
Under "Not sure if this is a bug or on purpose," PlumBots that have the Sentient or Friendly chips installed can't help out with addressing baby's/toddler's needs. The game simply pops up the "No Interactions Available" box. Seems only PlumBots that have the RoboNanny chip are able to take care of kids.
And the final issue I found isn't really an issue so much as it is a nit-pick. It seems the PlumBot chip Musical Machine doesn't include the Violin in its collection of instruments. PlumBots that have that chip won't play at Level 10 and will forever be stuck at Level 0 unless they have the Limitless Learning chip installed. Kind of wish that wasn't the case, but like I said, it's more a nit-pick than anything else.
