I know this is adding a review 3 years later..., however I tend to try out a Jenny deck whenever a new release is out to see what has changed. Considering we are heading into rotations, it might be a good idea to look at current legacy cards to review whether they can be revised and avoid future errata.
Even with newest card pool, I still rank this as one of the worst weaknesses. If I want to pass, I either need to build for basic investigations (no using lockpicks), have a friend that has high intellect, or add in Streetwise and/or Well Connected, which still require more time to setup compared to other investigators. It's especially bad in lower player counts where the loss of actions mean more, especially with the chance for failure. If this weakness was on what people regard as an S-Tier character I might not be as bothered, but I don't think Jenny is in danger of that. I say this as someone that really likes experimenting with Jenny's dunwich investigator versatility (5 non class cards).
To be clear the problem with this card is you spend actions to go to the location. You spend two actions to do a basic investigation. You may fail and then have to spend two more actions. You will likely need to raise your intellect stat to consider the attempt which means drawing the right cards and building enough money (the smallest of the issues). The best solution is a friend that might be in the area with a high intellect that somehow isn't busy. The only other card I can currently think of that is as problematic is Roland's Cover Up
I can think of multiple ways to "fix" the weakness that are thematic (IMO), but don't think this is the area for that kind of discussion.
I originally considered this a design fail from early in the games life, however the more recent advanced version, Searching for Izzie is also a problem.
I did figure out that if the weakness lands on a 2 shroud location and I have two Matchbox assets I can just succeed, but I don't want to be forced to build cluever Jenny losing two of my off-color choices, as part of her appeal is versatility to choose different build.
This is definitely a good choice for a cluever Jenny as those cards can support other investigators. If Scavenging is one of the off-collor choices, they even can be reused and re-equipped as fast actions with Joey "The Rat" Vigil, who I consider Jenny's better "signature card" when considering her ability to gain a resource.
