Collectible Card Game Headquarters

Describe the Bug:
Multiform Wonder's P/T pump abilities have no effect.
Attempting to activate the keyword-granting abilities crashes my game (with no dump)

Which card did behave improperly?
Multiform Wonder

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Manalink dev 778ccb5 version - duel

What exactly should be the correct behavior/interaction?
Abilities can grant P/T manipulation or keyword abilities until EOT

Are any other cards possibly affected by this bug?
-

Here is the .dmp file generated when you activate Multiform Wonder 's ability to grand flying, vigilance, or lifelink ability:

About the 3nd ability boost/lower power or toughness, I want to add that after you pay the energy counter there is no prompt.
Also remember this ruling while fixing both abilities:
Rulings:
9/20/2016
As you activate one of Multiform Wonder’s two activated abilities, you must announce which one you’re activating. However, you don’t choose that ability’s effect until it resolves. For example, you must announce that you’re activating Multiform Wonder’s middle ability specifically, but you don’t choose which of the keywords it gains until the ability resolves.

Fixed the crash only in commit cc50dbb.
