When using the same verb name but a different path and category it will fail to register both verbs of the same name. Right now I am making a "tutorial" of sorts on things and I frequently use "One" and "Two" to show that it is the first and second part of the example. However when it is compiled, the last verbs added to the list overwrite the original.
set category = "Example One"
var/result = "Hello"
world << result
set category = "Example Two"
var/A = 0
Two Tabs with the verbs "One" on each.
You get the tab "Two" with the verb "One" as if the One / One had been completely overwritten.
Addendum: Even if you give the path different names, but use set name="One" it will overwrite the first "One"
