Write multiple no longer works with 0.2.331

[Eldarion85]

After upgrading to 0.2.331, Write multiple no longer works. With every input I get the message "Write multiple as array session is not active!", which unfortunately doesn't help me.

After downgrading to 0.2.330, it works again straight away.

Can you attach you flow or simplified one?
I would check it and use it to debug my nodes (action).

To write values msg.topic should be "writemultiple"
