Hi, I'm the GM in the above comment. My first thought was making crew upgrades cost 1 less coin, but that seemingly small change might make Hardcase too powerful to justify its current placement on the prison claims chart.
I like that. It's sort of like the new version of Patron, but you have to go to prison to get it, so it's okay if it's pretty strong. I'll make a change in the next update. Thanks!
