So this bug has been around as long as I can remember, couldn’t find an existing report on it though.
The bug is caused by swapping in utilities that are also used underwater but in a different slot. Example:
slot: 7 8 9
skill on land: A B C
under water: D E F
I use skill A on land and it goes on a 1min cooldown, then (out of combat) I decide to change slot 9 from C to D. Under water skill D occupies slot 7, but changing slot 8/9 on land to this skill will copy the remaining cd duration of A.
This is the same for sPvP and PvE/WvW.
@attachment:
first one is underwater with Corrupt Boon on 7, on land I activate Spectral Armor then change Epidemic for Corrupt Boon and it copies the cd of Spectral Armor.
