Sorry if this has been resolved before, but I searched around and didn't find anything. A while back, I downloaded the Prism Art Studio (legally) but when my Sims use the glassblowing station, they just stop doing anything and just stand there. I do have some mods installed, I was just wondering if anyone else came across this, and/or if anyone knows which mods could cause it.

Thanks!

I'm assuming you are at Patch 1.63-67 so I guess the first question to ask you is are all your mods up to date and at the same level as the patch you are using? Have you tried updating your comerged.package file?
You can get an updated copy of that HERE The download is at the bottom of the page
Have you cleared out your cache files recently?

I had the same problem. Even redownloaded and reinstalled all my store content for nice, fresh, shiny ccmerged.package. Didn't work. Never figured out the cause. Moved on with a pledge to stop wasting money on broken crap from the Store. And meaning it. Really. OK, maybe the tea house, but then that's it.

Anyway, I'm having the same problem. I originally had a copy that was giving me the giant cube glitch (same place I downloaded from had a link to a working fix in comment section https://www.youtube.com/watch?v=a3ANPDpWm24) and the package with the weird foreign title fixed that (don't download the more recent patch; it did nothing except override other overrides that WERE working) but the interactions are still canceling themselves before glass blowing/smelting/whatever is completed. I have Master Controller, and that let me see that the Artisan Skill isn't there, so I highly suspect that's related to whatever the culprit is. I had a similar issue with the violin skill at one point. Yes, my ccmerged.package is up to date, yes, it's the Nona's copy, yes, I've even tried reinstalling everything and running without any mods. The interaction still cancels. When something goes into the furnace, it doesn't come out. Hope this helped some of the other detectives out there. I think like the cube, I just haven't found the right fix yet, so post any link that seems to patch through the Artisan Skill.
