PSA / BUG: UADx plugins reset to default on drag-and-drop in 8.2 & 8.2.1

[studioarmadillo]

Hey everyone, just a quick PSA for anyone pulling their hair out over UADx plugins resetting during a mix.

The Issue:
In Studio One Pro 8.2 and the latest 8.2.1 update, dragging and dropping a UADx plugin to duplicate it to another track fails to serialize the VST3 state. Instead of retaining your tweaked settings, the newly copied plugin resets entirely to its default parameters.

Testing & Isolation:
I’ve verified this issue on two separate studio computers. The bug appears to be isolated to UADx plugins—other VST3 plugins like Waves and FabFilter retain their settings perfectly when dragged and dropped.

Support Status:
I have already submitted a detailed report to Tech Support (Ticket #1035604). The support team confirmed the issue and it has been officially escalated to the QA/Development team.

Workaround:
If copying UADx instances is a heavy part of your workflow, the only stable solution right now is to roll back to version 8.1.2, where the drag-and-drop state serialization works flawlessly.

If anyone else is experiencing this, please reply to this thread so the Community Managers can see how many users are affected and hopefully bump the priority for the next patch!

I was experiencing the same thing in 8.2.0 (works fine in 8.1.2) and also reported to Support. 8.2.1 partially solved it - you can drag-and-drop now but all UAD plugins still revert to their Default preset when you first instantiate them. If you have your own starting point presets saved as Fender Studio presets (like I do) you need to save them in UAD plugins preset and then right-click it and choose "Set as Default Preset". Only then the UAD plugins will open with your settings. For some unknown reason they completely ignore Studio Pro's default preset since version 8.2.0.

EDIT: I've updated my UAD plugins and the issue is back - you can't even drag-and-drop without losing settings...
