Game Mechanics: song stacking issue

[Pescador]

In classic, you were able to click off a song in your buff window, and then immediately replace it with a non-stacking song. This was advantageous when you need to switch between Selos Accelerando and Selos Song of Travel.

I've noticed that if I click off lvl 5 Selos, I am still unable to receive Song of Travel until the full duration of Selos has passed. So, if I want to immediately switch to Song of Travel to cross some hills or whatever, I have to turn off Selos, wait 3 ticks, and then I can use Song of Travel on myself.

Even after clicking off the Selos buff, I am getting the "Your spell did not take hold" message until the full duration of Selos has expired
