[FIXED] [SoD][Tarragrue] Boss buggs out after being pushed during Mists

[FreakzStaff]

**Description of the issue:**
The Boss starts doing nothing when he gets pushed to less than 10% while he casts Mists.
**----------------------**
**How it should work**
Mists should stop, and he should start casting the Chains. When Chains end he should start doing his normal Stuff again
