I'm guessing this will be more about the Console than the DL3...
Hog 3.1.9
DP2000
I setup a 2x1 collage completely.
I wanted to 1st save it to a Pallet (with the CAL grid).
Record Beam, USE P, USE C, USE B, Select Beam 1 in Pallet.
(contains both Motion, Global, and Graphic 1)
After naming that pallet,
Record Enter for Cue 1 in my Cuelist.
(with the cal grid showing)
Go on to program a cuelist of video.
All is good.
Next day, bring up the system.
Roll Cue 1
Grid alignment is slightly off.
(Tilt on one fixture may be a bit loose, no problem.)
Tweak the Keystoning on right DL3,
Record Beam, USE P, USE C, USE B, Select Beam 1 in Pallet.
(the one used in Cue 1)
Select MERGE on the prompt.
BLIND the console, and it reverts back to being slightly off.
Do a View Cue on Cue 1 and confirm it is referencing the Beam Pallet.
Hmm?
Had to move on, so I ended up merging the change into Cue 1.
