I'm pretty sure this is possible because there's a way to remove duplicated text (which you have no idea which is duplciated, like here) in NP++. I've used it quite a few times but the problem is just that. I don't want it to delete the duplicated text.
"I clicked on something twice, it must be copied!"
It did copy. Another lead of a duplication:
complexBuild[64, 2] = brick1x2crestLowEndData 0.5 0.25 1.1 45 0 1 0 0 0 ;
complexBuild[65, 3] = brick1x1fData -1.5 0.5 0.3 50 0 1 0 0 0 ;
64, 2 shouldn't be there. It should be 64, 3 meaning that the count is offset by one.
I really need to add duplication-checking to the tool.
