When clicking the buttons to move units and then undoing it, the final result shows a line for that unit but saying "0
" for instance
Like this
From system 305 (Loki/Ashtroth/Abaddon (Devils))
Moved 1
Moved 0
from the planet Abaddon (1/0)
Moved 1
Moved 1
from the planet Ashtroth (3/2)
Could it simply be removed from the resulting list?
Moved 1
