Game Mechanics: Buff Stacking Issue

[Colgate]

occasionally my buffs will revert up to slot 1(as they should with the recent patch)

also occasionally, they will stay in the same buff slot

i have no idea what causes this

[Ele]

might have something to do with the counters on buffs now?

[Mac Drettj]

a recast should, if i understood the patch, erase the old and relocate at first available opening

dont think counters have anything to do with it

Haynar: Made some spell stacking more classic, for refreshing identical spells. The old spell will be faded first, and new spell will be put into lowest slot.

edit:

its not doing it with grim aura / see invis at least

slot 1: empty
slot 2: see invis
slot 3: grim aura

recast grim aura and it reapplies at slot 3 (same as before)

so maybe counters

Noticed this too with some casts, usually self buffed on my wiz. Could not figure out what would change my buffs from refreshing in same slot to going to top slot every time. Still get occasional strange placement. Did notice but not confirmed that when the buffs would be just refreshing instead of restacking if I would zone while working my buffs up, when I crossed the zone line my buffs would start going for top slot.

HPT and I have noticed okiels radiation causes this more often than not

[Colgate]

doesn't seem to matter what "level" the buff is

i've seen it happen with see invis, monk epic clicky, levitate, DMF, sow, symbol of marzin, etc.

no idea what causes this and it seems sporadic

[Ragnaros]

it only does it sometimes for me

[Lasher]

It always does it to me about 50% of the time

[Nirgon]

update: 100% of the time this will happen 15% of the time

I ended up with a top slot dmf

UPDATE :

If I'm in a zone the first time I refresh any of my buffs they will move the 1st slot, and afterwards they will cover the slot they are already in.

EXAMPLE :

Enter a zone, I have jboots 4th slot, if I click them again it will move to what ever the "top slot" is.

After this, clicking them again will not move them, but simply refresh the timer.

EXAMPLE:

enter new zone, click telescope to cover my top slot and put jboots on behind earing/aon in 4th slot.. from there I can freely click my jboots with out them moving down. Until I zone again.
