Roadhog & Full Boar server disconnection while editing loops

When editing a running loop ( 3 cues with a link to cue 1/forever) in a 30 Cue List the server disconnects when opening a cue of the loop with open + mouseclick on the cue or with "CUE 3 OPEN" . Console is running properly but no DMX output on the super widget due to the disconnected server. Tried on 3.1.7 & 3.1.8 on Roadhog and Full Boar.
