Help with spell stacking: Listless Power and Augmentation

[noudess]

I'm trying to understand why the GUI overwrites augmentation with Listlesspower, but the server does not.

I turned on stacking logs and got this:

[06.11. - 11:55:53] [SPELLS__STACKING] Kincar: Check Stacking on old Augmentation (10) @ lvl 29 (by Kincar) vs. new Listless Power (162) @ lvl 29 (by Kincar)
[06.11. - 11:55:53] [SPELLS__STACKING] Kincar: Augmentation (10) blocks effect 1 on slot 2 below 100, but we do not have that effect on that slot. Ignored.
[06.11. - 11:55:53] [SPELLS__STACKING] Kincar: The effects are the same but the spell types are not, passing the effect
[06.11. - 11:55:53] [SPELLS__STACKING] Kincar: Stacking code decided that Listless Power is not affected by Augmentation.

While on the GUI - listless power overwrites augmentation, the server keeps both us. This makes it very hard for players to tell when augmentation is really down.

2 questions:

- do they stack on live? I don't have the right class to test with.

- If they are supposed to coexist (fighting each other essentially), does that mean the stacking code is broken?
