Discord version is 3.0.4 for 1.7.10 and 1.12.2. I have configured discord integration on several server to the same discord channel. And I've re-used bots by changing their nickname in discord integration and renaming them in the discord web app used to manage the bots. However, I noticed that in game the original bot names is used instead of the nickname. that it is in discord. I did this to save some time and re-use bots instead of creating new ones and deleting old one.

So this might be more a feature request rather than an actual bug.

i think this issus is link with : #101

Yep.. I believe you are correct. I didn't catch that was the same issue.
