Fun thing I learned a little while back with Tia Portal V13, don't use HMI reset buttons inside of the safety program directly. Make sure to map it to another bit inside of a standard function first, then use that bit inside of the safety logic.

Not having the HMI input synchronized with the scan cycle would sometimes give us a major PLC fault for the safety telegram error.
