What you were expecting to happen, and what actually happened:
Based on the 4.1 patch notes, previously, effects that say they should occur on skull damage were actually occurring when skulls were matched, and this was fixed. However, based on the wording of the first trait on Titan (forget which tree), it causes stun when hero takes skull damage. Instead of that happening, the stun happens whether damage occurs or not, even when hero has barrier.
How often does this happen? When did it begin happening?
Every time, any mode.
Steps to make it happen again
Match skulls while hero has that talent selected while hero has barrier. It may work like this against entangle as well, haven’t tried.
