I confirm the same bug occurring.
[Game][Minor] HP Potion Timer doesn't function when at least 2 potions are used.
-Activated an HP Potion.
-Moved around a bit.
-Activated 2nd HP Potion.
-Timer for 1st HP Potion used was stuck at 100% Time Remaining. (However, it seemed to be a visual glitch, because)
-Upon the first HP Potion's timer being expended:
----> Timer refreshes and 2nd HP Potion Timer works as it should.
Since the visual timer(buff icon) is the only thing giving problems, likely you would want to start looking at how the "real" Potion timer works in handling timer-data, make sure it's sending the appropiate values to the "visual timer"(buff icon). If that's not it, there's also how the "visual timer" perceives the received data; since it's working fine at 1 potion, focus on the section of the codes that are different from the 1 potion to a 1+n potions, it should make it easier to pinpoint.
I'll test some more later, in-game.
After further testing, I can confirm this happens for both HP Potions & MP Potions.
Additionally, it seems only the 1st potion in Queu is glitched.
-->That is, if a player successfully uses an additional 5 potions before the first timer reaches zero(that is, 6 potions in a row).
------> The first potion is "discarded" or "eliminated from queu," thus the timer is refreshed & the visual glitch removed.
-----------> Timer works as should.
However, upon reaching zero again (consuming the entire buff), the glitch can again occur as before.
