Mercenaries not casting Curses if player has a curse up first, even if merc has +number of curses.

As title says: Mercenaries are not casting curses if player has a curse up first, even if merc has +number of curses.

If I let merc cast first, I can cast mine and both are up.
But it won't cast if I have my curse up first.

If I let my curse run out, he will cast it again.
But I'm using mark now which does't run out.
And I shouldn't have to let it run out anyway.

Maybe it's on purpose to not overwrite the player's curse, but the whole point of picking a merc with curse is that he should cast it.

Either change so merc casts normally regardless if a player has curse up.
Or make it so the merc can know if it has +curse items.
Or make a toggle next to the curse in the merc UI.

Anyone has a different experience? Maybe it's just the current merc I'm using.

I'm seeing a similar issue, except the mercenary is not casting their curse because they have already applied a curse (Curse on Hit gloves equipped to merc), even though they have +1 curses from a ring.

This is happening with at least the cruel mistress mercenary.

I will sometimes see 2 curses on the mob, which I assume is when the mercenary initiates with the curse skill before hitting the mob and triggering the gloves.

Similar issue. Was hoping for cruel mistress to apply both her despair and temp chains from asenath's when I would put doedre's daming on her. But she just applies TC and no despair gets cast.
