Bard Invis song not working properly after patch

[Acrux Bcrux]

Bard invis song is having issues after the recent patch. You cast the song and it will invis you fine, but as you leave it playing, the next 3 ticks of the song will not land on you and you receive the message "You tried to cast an invisibility spell on you, but you are already invisible". The song itself then wears off of you in its 12 second duration and the next tick of the song will reinvis you rather than hitting you every tick of the song and keeping you invisible.

I can also attest to the bard invis song "Shauri's Sonorous Clouding" not currently overwriting itself, as it has previous to the patch. This is causing a 1 - 6 second gap in which the bard and/or party will lose invisibility until the next tick of the song.

It's affecting Selo of Travels too.

Karnas said that travel song was fixed pending update, but not sure if that change will work to fix the normal invis song too.

Isn't working as Acrux described.
