"Enduring" mana flask "of Warding"

Pressing the flask button multiple times will queue the uses and they will be used one after another and will not be wasted. If this is intended, then the curse immunity should also last across all uses, but it doesn't. It ends after the first use. The flask is active, but the curse immunity isn't.

I'm pretty sure it was different before the last patch.

I am using an Enduring Flask of Heat which I need to keep up all the time because my mana regen is too low. I got frozen several times too in the last week, but I shrugged it off to (de-)sync problems.

[edit] wording changed to clarify what I meant

They’ve said this isn’t a bug. The mana recovery will queue multiple uses, but the flask effect cannot be queued.

Do you know if the same applies to "increased crits during any flask effect"?

I’m sure it would be the same. It’s the flask effect that doesn’t queue.

I think so too. It's the secondary effect that does not queue. The flask description doesn't make clear there is a distinction and it is only about the primary effect. I'll report that in the spelling/text-thread later if it isn't listed there yet.
