Eldrich Empowerment is Interrupting ES Recharge

Pretty much in the title. Don't know when this started happening, but any spell I cast interrupts my ES recharge. The skill states this should not happen.

I figured it out. Event Horizon is conflicting with it which states that I loose 3% of max life and ES when using a chaos skill. One would think this shouldn't cause ES recharge to be interrupted due to Eldrich Empowerment, but it does. This was a costly annoint and has caused me many deaths. I don't feel that Event Horizon should prevent Eldrich Empowerment from working.
