Runesword no prevent regeneration & no exile

[Aswan jaguar]

Describe the Bug:
1- Runesword doesn't prevent the creature dealt damage by the creature targeted by Runesword to regenerate.
2- The creature dealt damage from the creature targeted by Runesword if it dies it doesn't get exiled.

Which card did behave improperly?
Runesword

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?
1- If the creature deals damage to a creature this turn, the creature dealt damage can't be regenerated this turn.
2- If a creature dealt damage by the targeted creature would die this turn, exile that creature instead.

Are any other cards possibly affected by this bug?
