Im curious , As I use BCUT to make them. But there are few things can mess-up a script, but None of the Betas ever said anything, HMM.
This got me to checking ALL our SFRD carrier files. I wonder if His scripts\ftb-Carrier.py, could have got messed-up, it is called by EVERY carrier file.
Did the reuired workbee-shuttles, get installed?
Did the Problem stilll exist , even after installation?
