this is a glitch with color, fisheye, whirl, and all other in that block, very minor tho. so if you have something that is like,

when green flag clicked
forever
change [color v] effect by (25)
end

if you would drag that it would not continue to do that, but if you then put the sprite back down, it would fast forward and it would be completely different (a better example would be anything but color. i f you would like to know more about this pls let me know by added on to this topic
