Bug : Ninjutsu skill causes game to crash

Hello,
I'm currently playing Forge version 1.4.3 and recently tried to build a quick U/B Ninjutsu deck that used unblockable creatures - however, whenever I manage to successfully put a Ninja into play during the declare blockers step, the game crashes and gives me an error report. I also had this error on Forge version 1.4.2 - while it seems to apply to any card with Ninjutsu on both versions I generally get this bug to happen the quickest by using Mistblade Shinobi 's Ninjutsu on Invisible Stalker or Tormented Soul.
