The Server Hangup encounter takes place in the Shamanist era. This encounter is particularly useful for the Mechanic class, because it can give access to some particularly useful machine blueprints.
A crumbling building with a still-functioning database of blueprints for building simple machines and tools is found. While the character is trying to access the valuable information therein, the server locks-up.
The character can try and fix it, or simply take the still-functioning electronics.
