I think I found a bug with selection boxes,
steps to reproduce :
-
draw 3 empty elements in a row
-
Select them with a selection rectangle (shift-drag)
L.I.N.K crash with this error message :
./crazy.agpack/main.lua:1225: attempt to compare two nil values
stack traceback:
main2.lua:277: in function <./data/main2.lua:111>
