siege cascade disables area transitions

When on left mouse, siege cascade completely disables the ability to transition between areas or even click on waypoints to move around in an area.

It took me around 15 min to discover the cause... Weird bug, lol.

Anyhow, here's to hoping it's not hard to fix. I know it's kinda a niche scenario but I do think it's important to be able to slot the skill where it feels most natural to activate in my rotation.

edit: after some more testing it seems to happen whenever a "reload" action is placed on left mouse... so it's not unique to siege cascade.
