Default routine doesn't cast auras for 100% mana reserved

[PainfulDeath]

Ok, so I've figured out why exactly the routine doesn't like to cast all 3 of my aura+2heralds (all the time it only casts 2 of those and refuses to cast the 3rd)
After setting the "Debug auras" checkbox, this line started appearing and it explains stuff:

[CanCast] We cannot cast [AuraName] because mana x < x+1. (I removed the aura name and numbers)

While the client sees the aura as castable the whole time and I ofc can cast it by hand - the bot thinks it cannot cast the aura and proceeds to think that way, while repeatedly outputting that same line throughout the fighting. Seems like a rounding issue. Where can I (if I can) forcibly remove the mana cost check for now?

Same here

here's the exactly message when i'm trying to cast Hatred(50%) with a determination (50%) already on.
[CanCast] We cannot cast [Hatred] because mana x < x+1.

also can't use 2 auras 50%+50% ( I have axe "Soul Taker", and I don't need mana

This is mentioned on the Release thread, but I'll mention it again here:

BUG: There was a previously known bug with mana calculation when using multiple auras and various reductions. This has not been tracked down yet, but the bug resulted in some skills not being used (under-estimation of current mana). This is still on the todo list, but did not pose a release preventing issues.
