Interesting situation. We were playing with ХВ rules. The opponent outsmarted me and ran away. When I asked how he managed to escape, he replied, "You cast everything first, following the rules." Well, okay, maybe the opponent wasn't aware of hit-and-run tactics. But how did the ХВ rules allow that?
It's better to write about ХВ rules here:
/topic/10609/.
I checked – I couldn't reproduce it on versions 3.807 or 3.716. Can you tell me more about the situation? Even better would be if you could provide a save file so I can check.
