EOS Crash when using offset command on Multi-Cell Fixture Group

Hello

Running EOS Family 2.7.4 on GIO

Wondering if anyone can recreate this.

Direct Select Group 71 (Multi Cell CYC Lights) > ANY Offset command crashes to the shell.

All good with non Multi-Cell groups

also when selecting the CYC lights via command line and using offset commands works fine.

I should specify only tried using the offset commands on-screen 

I will have access to the console in a few days, can get more info.

thanks.
