Module randomly stops working

[SeinRuhe]

Hi! I hope everything is going good for you!

I was testing this module, and, when the fastskills option is enabled the module stops working while the autoattack key is pressed, needing to stop pressing the key and hit the key again to make it work again. Sometimes it stops after a good chain of skills, sometimes it stops after casting just one skill.

This doesn't happen when fastskills is disabled!

I'm running a clean install of the Toolbox, without any other modules besides this one, it's dependencies and SharedState.

Any idea why this might be happening, and how to fix it?
