This bug was fixed in Patch 1.52.100
My Sim has the task to meet with a client/class to turn in the work they did.
Instead of doing the interaction, they T-Pose and throw a lastException
The issue only occurs for Vampires. It could be connected to the whole night/day issue.
For the moment it’s best to play the career with a non-Vampire Sim.
It might be possible that meeting the client at night works but I haven’t tested that theory
