Tenno,

The team has been raising old topics when time permits, and we've come across some specific older feedback about  🥶 COLD STATUS EFFECTS! Back in the day (in 2016 to be exact), we put a topic to rest that 'Cold Status Effects prevent other Status Effects from being applied, because the target is frozen solid'! Time goes on, and this topic was re-reviewed. Currently on live: If you freeze an enemy with a Cold Status Effect, you cannot apply any new Status Effects until that is done.
Demonstration:

Coming Soon: If you freeze an enemy with a Cold Status Effect, you can immediately apply other Status Effects!
Demonstration:

Other Minor Inconsistencies we are fixing:

Currently on live: If you hit an enemy with a Status Effect (like Toxin) then Freeze them with a Cold Status Effect, it prolongs the duration, but only if you got the Status Effect in before Cold hit. You could never apply new Status Effects while an enemy was Frozen, which was detrimental in many ways to builds and teamplay. These Status Effects will run their normal durations for consistency after this change, while allowing new ones!But wait, there's more! This also changes the way Gara's Targets and Atlas' Petrified Targets react (i.e they now get this new behaviour).

@[DE]Rebecca Does this apply to the other "freeze"-like effects (such as Gara's vitrification and Atlas' petrification)? 

Yes, it does.
