Are you using the mod against a singleplayer or multiplayer world? To confirm the mod is correctly installed check the controls menu to see if you see the key binding. If you see it then it is correctly installed and so should work.
Looks like my fix for Forge has been rolled up into a release so you should be able to load a vanilla world into at least version 184.108.40.2067 of 1.8 Forge and the bounding boxes will be accurate for nether fortresses.
irtimaled, thanks for this mod it is wonderful and very well done. but with that being said i had some problems with 1.7.10 version of your mod, i raised two issues on github see here and here. but then decided i would try to fix it myself, so i forked your github and applied all the patches myself and ran it, and it worked fine no crashes or anything wrong. so i think(dont know for sure) that the problems is somehow the code recompiled wrong, i have my zip containing the working version, if you want i can post or show it to you in a pm. thanks
I think this is because I built against a newer version of Java - I plan to release an update in the near future now that MCP has been updated to 1.8.8 - will target an earlier version of java to avoid this in future.
@FatherWh0 I've no experience with spigot/paper but happy to accept pull requests on the GitHub repo. Of course if you have the dat files from the server you can use the vanilla version with the "local dat files" option described in the documentation.
I really like this mod, i use the forge version but i am having trouble getting it to work loading the dat files for my server. Is the correct folder path config/BBOutlineReloaded/ip/port ? I have my dat files in the port folder but it doesn't work. Using cache works fine but I'd prefer using the dat files themselves.
Also when I put the mod on my personal server, it doesn't crash me or the server but I can't join and I get this error in the server console.

Really good mod though, love using it for farms in vanilla.
