Cold snap cast on freeze NOT consuming frozen status and not allowing additional freeze buildup

I am having a variant of the Cast on Freeze + Cold Snap bug with an additional interaction that I haven't seen reported yet.


Casting frost bolt at a new target builds freeze, when a frostbolt would trigger the frozen condition, cold snap goes off and the frost bolt disappears as though consumed by cold snap. The other two frostbolts move on as normal.

Despite cold snap being triggered and the frostbolt being consumed, the target remains in a frozen state and does not build additional freeze for several seconds after thawing. The frostbolt consumption occurs almost immediately on contact with the target once the freeze status would be applied, and the freeze immunity period seems to block freeze buildup from all other spell sources at my disposal (ice nova, freezing shards, frost wall).

This interaction was tested with and without scattershot, both resulted in the above behavior.

The interaction behaves as though the cast on freeze is triggering once the meter for freeze has been filled, but before the frozen condition is applied to the target. The damage applied to the main target seems low compared to manual cast of cold snap, as though the explosion damage from frost bolt is the only damage being applied. Manual cast of frost bolt and cold snap almost always kills the zombie enemies in sandswept marsh with one rotation, whereas the bugged combination leaves them at 60-80% remaining HP.

After testing this interaction further, I feel more strongly that the frozen condition could be getting added after cold snap goes off due to the interaction with multiple targets in close proximity. In this scenario, the first target experiences the bugged interaction and remains frozen. A new instance of frost bolt passes through the first frozen target dealing minor damage before hitting the new target behind it, causing the bug to occur again on the second target.

However, in this instance the original target has his frozen status consumed by the second cold snap trigger and shatters. The second target remains with the frozen condition and immunity to freeze buildup.

This scenario occurs on my character with and without support gems socketed for frostbolt and Cast on Freeze colds snap.

The full interaction does not happen 100% of the time, and could possibly be due to enemy type or enemy resistance levels. Both interactions occurred on almost every target in Sandswept Marsh where many enemies have a red frost resist icon. In Chimeral wetlands, the enemies were staying frozen after the proc, but I was able to stack freeze again as soon as they thawed.
