Blight Bosses in Maps Immune to Stuns/Freezes/Petrify

See Title

Was Running T16/T17/Originator T16s with Blightheart, Invigoration, Titanic Scarabs all day yesterday with no issues

Today, weve done 10 maps in a row with no mods like "cannot be stunned" "cannot be slowed" "action speed cannot be reduced below base value" etc.

Standard Blight setup, chill tower freeze + stun + meteor burning ground

My character has 100% chance to chill + freeze and no matter what we do, everything just walks right on by as if theres no towers there.

I would just assume its very difficult content (BECAUSE it is very difficult content) except it worked all last week with 0 issues.
