Hello, there! Long-time lurker, first-time poster, so I'll seize the opportunity to say thanks to all who contribute to this great forum in general, and to highly useful threads/projects like this one. That's very much appreciated.
Here's an issue I stumbled upon but haven't seen reported here:
Assassins can do a "Backstab" on Ice Balls. This hardly makes any sense, so I doubt it is intentional. What's more, from my experience, the supposed "back" of the ball is always a specific spot, as 2 Assassin stacks will do their backstab from the exact same hexagon even if the ball is accessible from anywhere.
Edit: That's before the patch was applied, and I have not applied any mods or user-made fixes yet. To clarify, I have the patch installed, but it says that it'll only be applied once I start a new game, and I'm still in my first game I started the day the game was released.
