[fixed]Felidar Umbra activated ability no attach to target

Describe the Bug:
I have fixed that Felidar Umbra couldn't be activated in latest dev but when activated ability resolves it doesn't unattach from enchanted creature and attach to target creature.
Maybe related to Prison Term bug here: viewtopic.php?f=86&t=22631&p=229086&hilit=prison+term#p227006
Which card did behave improperly?
Maybe attach_aura_to_target or Felidar Umbra
Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Manalink dev 518234c9 version - duel
What exactly should be the correct behavior/interaction?
Felidar Umbra activated ability unattaches it from creature it enchants and attaches to target creature.
Are any other cards possibly affected by this bug?
The same bug has Bound by Moonsilver.
No savegame as my savegames don't work for others, in fact most of those that are few weeks ago don't work for me either.
