Tixx Infinirarium, no credit received

Just finished the above event dungeon, won it, destroyed Toxx, got 50 presents but did not get daily Infinirarium credit and did not get credit for destroying Toxx (Festival Automaton).

Did the one where you need to give the princesses, toys.

Same here, got the instance reward but no achievements.

Done Toypocalypse (not quite at 30 rounds yet, but pretty close) AND Tixx's Infinirarium, same here, no annual credit given for Toxx, but did get instance rewards. Thought maybe I didn't tag him or follow instance instructions, so I did Infinirarium two more times, making sure to participate and get credit for each event, plus tagging Toxx with unstable presents and weapon skills AND trying to draw the xplod-o-bots. Really don't want to have to solo Infinirarium, it's a pain in the candy cane.

The 50 present reward can be obtained without doing anything at all so getting those doesn't really provide much clue.
