Patch notes & cập nhật Idle Champions of the Forgotten Realms

Thanks for the reports, and sorry for the inconvenience! The only change from the previous v656 changelog is a bug fix for the 0 HP blocker bug that we encountered in v655.

We've temporarily rolled back to v.655 to see whether this fixes the boss bug blocking some players' progress. We'll work on an updated build first thing in the AM, whether or not this resolves it.
