I'm trying to get this to result in this but instead I get this.
Can someone help?
I think I fixed it for you. The redirect url looked like it was using the hex code for the parentheses instead of using (). I had to change the link from:
[[Sistermon Blanc#(Awakened)]]to
[digimon.wikia.com/wiki/Sistermon_Blanc#(Awakened) Sistermon Blanc#(Awakened)]
The link you originally had should have worked. I suggest contacting staff to report it as a bug.
