Hey ,
If you check my post again you’ll see that I am using NotifyQueue, directly below the depreciated line you mentioned.
Animation->NotifyQueue.AnimNotifies.Num()
NotifyQueue also no longer works, which is why I created the topic.
Animation->AnimNotifies was actually depreciated in 4.11, so I switched everything to use NotifyQueue, but now in 4.12 neither of them work.
