Rpg Maker MZ user
I use the Visustella scripts but not the Visustella ATB plugin. I added the linked parameter as stated
<Dual:linked,15,275,16,236>
But I don't know why the second actor ATB gauge don't empty
Let your actors combine their skills in RPG Maker MV and MZ · By
Sorry its a typo.
I have the version 1.8.1 of RMMZ. It work fine with the ATB active but not the ATB wait. The character who cast the skill can cast it even if the other member don't have a full bar (it doesn't behave like this in ATB Active) or don't wait for the other character to have their bar filled in order to cast de dualskill. It behave like if the linked parameter wasn't there.
No repro; I saw the bars for both characters empty with a linked dualtech. Granted, I'm not using some of the plugins you have active; let me try those and see what happens. EDIT: Nope, works fine for me.
(The newest version of MZ does not address your issue, since I couldn't actually reproduce your issue at all. It just addresses something I discovered while trying to look into it.)
