Game Mechanics: Buff client/server desyncing, when debuffs overwriting buffs

[Nirgon]

best way I recreated the buff stacking issue is by letting a buff fade on its own (short duration stuff like DS is good) then rebuffing afterwards and zoning.

A fresh coat of buffs then zoning doesn't have any problems in every test I did.

is Res effects acting like a "debuff" in terms of buff stacking after being resd?

ya res effects acts as a debuff, however technically its always applied before any buff. OPs applying buffs first then debuff second. therefore rez has nothing to do with this scenario.

theres been a few posts about the relation between buff order and the client - there are other oddities, such as how if you have a buff in slot #3, but then click off your #1 buff, and refresh the #3 buff, itll then appear to jump to slot 1 on your client, but is truly still in 3.

got link?

I think the most pressing issue with buff stacking is a misleading post lead to it being in the current state.

The current state suggests that when a buff is overwritten by either a superior buff, or by a Debuff occupying the same slot, that new buff/Debuff will go into the highest slot that is open.

This is false, and shouldn't work like this. Nilbog even tested it:

Also if you want more evidence it wasn't this way on classic / Mac server with old code:

https://m.youtube.com/watch?v=6NyERUQeub0

From 4:30 - 7:45 in that video you will see Boost has bard Chorus + Rizlona's on in slots 13 and 14, with an empty slot 12 and 15.

Shortly after that 4:30 beginning mark, Chorus ends very briefly and restarts, this causes it to disappear for about a second in slot 13 and reappear in slot 12 (as one would expect when the buff fades and is recast).

Also from 4:30-7:45 you will see there is an empty slot 13 and Rizlona's stays active in slot 14 the entire duration. It is clearly being refreshed every 18 seconds (because bard songs), but is not jumping up slots after the first refresh where there is a void available in his buff list that would allow the jump.

-----

If they fix this buff replacing coding, you won't run into this issue where the server desynchs when it replaces a lower slot buff with either a better buff or a Debuff, trying to place that new effect in an empty top slot instead of the slot where you actually had the original buff like it should.

everyone agreed that change was classic, even you were fine with it 3 posts later (in that thread you linked). whether or not it made it onto eqmac is technically a different topic (same applies to ur vid). my guess is that this is just residual effect from the root issues, or else just a minor bug on haynar's implementation. Either way, something that needs to be looked into.

another great detailed scenario.

keep em coming. detailed reproductions is exactly what they need to pinpoint the few underlying root issues which are causing these oddities to be seen across the board.

Possibly related to this bug in which beneficial spells are blocking detrimental spells. Circle of Summer is blocking Occlusion of Sound & Protection of the Glades is blocking Breath of Ro.

Perhaps the buff stacking code should always drop beneficial spells in favor of detrimental spells when there is a slot conflict. The linked bug & OP bug indicates this isn't occurring server-side. The OP bug indicates it does, however, occur client-side. In some cases (e.g. OP bug), the detrimental buff stacks with the beneficial buff, when it should overwrite. In other cases (e.g. the linked bug), the detrimental buff is blocked by the beneficial buff, when it should overwrite.

bump. Terribly annoying having buffs appear the wrong slots. It screws up buff order and dispells, which a pita especially in pvp.

[Qtip]

Whats messing it upI think is when a buff has 2 effects and you get hit with a debuff that effects one of the buffs effects.

If you have dmf up and a necro casts scent on you. You then dispell the scent and click off dmf, you have an unlimited duration levi until you zone. Something with the poison debuff on scent effecting the +poi on dmf is bugging it out.

I dont know if scent is suppose to overwrite dmf. But Ive had scent casted on me and got dmf dispelled and stayed levi since kunark.

There is an issue with buff slots as they are read client side vs server side.

Currently it appears that the client does not force check correct buff slot placement vs the server properly. This is corrected on zoning or relogging.

Additionally, some spells cannot exist in some spell slot arrangements. The robe of the whistling fist effect sometimes does not appear though the clicky effect shows the song text in the chat box there is no cannot take hold message yet there is no buff icon and no effect from the buff. I do not recall this issue happening to me prior to attempting to frequently stack both monk epic clicky and whistling fist robe clicky.

Not sure if any of this is classic but as a monk its definitely quality of life.

Thanks
