Both bugs appear in the attached .lud.
1:
When I first try to make move number 4 the move is not executed, instead the piece I click becomes semi-transparent and the status tab tells me "Selected illegal move: [[Remove:type=Cell,to=30,decision=true], [Remove:type=Cell,to=21], [Add:type=Cell,to=21,level=1,what=4], [Remove:type=Cell,to=29], [Add:type=Cell,to=29,level=1,what=4]]".
When I click the piece again, the move is executed correctly.
The same happened when I first tried to make move 5.
2:
Move 6 is supposed to be illegal. It is a removal of a DoubleCounter, but the remove-region is an intersection with [edit: filter over] (sites Occupied by:Mover component:"Counter"), so how is this possible? It should only be possible to remove a Counter.
