[fix]Cannot block ability doesn't get removed-broken in dev

Describe the Bug:
If creatures gain cannot block it stays for good no matter if the conditions later change. Tested with cards like Togglodyte, Hazoret the Fervent and with Arrest. This is broken in dev only, in release they work fine (the first two at least work correctly).
EDIT: It seems that all sp_keywords are affected like this.
Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
dev based in commit b43e256
What exactly should be the correct behavior/interaction?
Are any other cards possibly affected by this bug?
