I also found a bug where you can use the grapple on Archeos, which also freezes the game.
And is it intended for you to lose characters you've unlocked after you die with them?
v0.8 ( which is online now ) should prevent the lvl10 bug from happening
I will check archeos interraction with grapple for next version.
When a non-adventurer character die, he goes back to jail.
