I'm not entirely sure what caused the bug in question, but it should be fixed now! I sent it to Kai to implement in the next patch, but here's the .cs file itself so you can start using it now, with a couple new features thrown in. Just replace the existing file with this one and you'll be good to go!
Edit: I didn't see there was a bug with Get Super Text mesh, here's that one too. Lemme know if you have any other issues for the Playmaker actions!
