Client Type (ex. PC, Android, Webclient): Windows Client Version (if known. Webclient has no version.): v2.7.1 When did you first notice the bug?: Today Have you been able to reproduce the bug?: Yes Information (include relevant logs, replays, screenshots): See Turn 13 in the log. (23:58:05) Annoying Orange: https://hastebin.com/adoyopidoh.sql (23:58:59) Annoying Orange: the mence was originally leftovers btw, and actually did give it a speed boost when it said its speed was boosted I was able to reproduce the bug in the following SS. In both instances, the error occurs when the item effect should happen at the very end of the turn (such as after a double switch). Chesnaught is holding a Salac Berry, so it appears that the item data is getting mixed up. Also, this is from ORAS UU, so it could be something that broke from a recent fix because I don't believe this bug has existed for all of ORAS.
Since some other users encountered this issue, just adding a few details: To reproduce this bug, say User A has salac berry, and User B brings a pokemon under 1/4 health (or after taking the hit of User A has less than 1/4 health) into the battle field and there is Stat drop on the holder of berries. User B will get the speed boost (as long as the health percentage of the true holder of berry is above 1/4) of salac berry. Same bug affects all kinds of +1 stats berries (Salac, Petaya etc) that activates less than 1/4 health. This basically says that the stat boost berries got activated on opponent when holder stat drops and the opponent has less than 1/4 health. Spoiler: How Stat Drop works in reproducing bug Start of turn 29 testingfsk called Garchomp back! testingfsk sent out Landorus-Therian! Landorus-Therian intimidates the foe's Buzzwole! The foe's Buzzwole's Attack fell! fsk called Buzzwole back! fsk sent out Garchomp! User double switches, but not intimidating on the holder of the berry so no swap bug. Start of turn 31 testingfsk called Tapu Lele back! testingfsk sent out Garchomp! fsk called Tapu Fini back! fsk sent out Landorus-Therian! The foe's Landorus-Therian intimidates Garchomp! Garchomp's Attack fell! The (No Item) raised the foe's Landorus-Therian's Sp. Att.! User double switches,and the mon with less than 1/4 intimidating on the holder of the berry so activates swap bug. http://imgur.com/a/fVa7t To better explain what I mean by "there is Stat drop on the holder of berries", see these pictures. If the true holder is above 1/4 and there is stat drop like Scarf Lando dropping attack of holder, or rock tomb hitting the holder, the bug happens. In the meantime, the original item of the intimidate ability mon will get nullified, say choice item no longer locks you into a move etc. Constantly switching the same intimidating mon to different holders would activate this bug repeatedly in one battle. The bug is global for both ORAS and SM.
