i happened to have this situation, where i my jump back activated, but the char was not moved. There was one free tile behind char, though he was close to the edge. Here is a picture, and you can see also messages in the corner. Character hit was a dwarf:
It took a long time for that image to load for some reason. Anyway, currently your Human Wizard is behind your Dwarf Warrior. This would prevent Jump Back. The little bit of the log I can see suggests that he was facing in this direction before being hit, and so there is no bug.
thanks for clarification. I thought that the jump should happen in direction from where attack comes, thus, in this case, dwarf should jump back and to the left.
Not a bug, just confusing. When "slide back" effects trigger on defensive cards, it tries to move in the opposite direction of that char's facing (which blocked by the wizard), not the opposite direction from the attacker. (I typed that with the picture enlarged, so I didn't see the other responses.)
