Observed behaviour

After casting Anti-magic Field, a counter appears that rapidly alternates the entire duration between 1 or 2 seconds remaining. It does not accurately track the remaining duration.

Expected behaviour

I expect that casting Anti-magic Field results in a accurate duration remaining counter.

Steps to reproduce

1. Join the Server
2. Cast Anti-magic Field
3. Note the incorrect duration counter on the screen

There is no way to track this duration in other way. If the area effect lasts for N seconds, and I make it to apply the potion effect for N seconds, then even if you leave the area, you'll still have the effect. This way it will only linger for 1-2 seconds
