[confirmed]Skyrider Elf or Echo Circlet-multiblock card prob

[Aswan jaguar]

Describe the Bug:
I have in play Skyrider Elf equipped with Echo Circlet and a tapped Wayfaring Temple AI is attacking with an unleashed Splatter Thug and 2 1/1 goblin tokens.I assign Skyrider Elf as a blocker then:
1- for a glimpse a multiblock card is created and destroyed instantly
2- my Wayfaring Temple becomes 1/1 and if I block Splatter Thug and so Skyrider Elf gets killed the Wayfaring Temple gets killed,too.
Here another report about other Wayfaring Temple bug: viewtopic.php?f=86&t=18568

Which card did behave improperly ?
1- Skyrider Elf or multiblock card
2- Wayfaring Temple?
Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2016/01/15: Battle For Zendikar v2,duel

What exactly should be the correct behavior/interaction ?
1- Skyrider Elf 's multiblock creature doesn't get destroyed/vanished.
2- Wayfaring Temple doesn't become 1/1 when 2 creatures are in play no matter if a multiblock gets destroyed.

Are any other cards possibly affected by this bug ?

It seems it is a global bug with multiblock card and creatures with X/X or 0/0 p/t when they are selected as multiblockers the multiblock cards vanish immediately and don't block.I encountered this also with Aeon Chronicler and with a debugged Beasts of Burden,too.
With the Aeon Chronicler I got also this dump error:

Also Wayfaring Temple and others with x/x count multiblock fake card creature cards it is obvious when you see multiblock creature of others to their p/t.
