1.16.5 (renewed) is still being developed (questionable right now), and lacks a lot of the features you can find in the 1.7.10 (legacy) version. As compared to the legacy version, it's more like a proof of concept for the time being. So switch to 1.7.10 for the full mod experience.
'L' is also the default key bind for Worldedit's cheat-sheet. Just rebind them, which you can do through the normal options menu in minecraft, and if not, look through the respective mod configs. I rebinded the Worldedit sheet to ';'.
Yes sir! Roger, Roger!
Alrighty, I added this info to the warhorns and harad pyramids page. Thanks for the heads up GreenCat!
After an hour of searching, warhorns do indeed spawn in pyramids. I doubt that it's a bug since I've found at least 2 different Harad faction warhorns and they are extremely rare, as you can see I got 11 mithril nuggets before I found my first warhorn, which I would think implies that it's intentional. Also editing wiki pages is pretty easy, believe me. you can read https://lotrminecraftmod.fandom.com/wiki/Help/Wiki_Code and study a page's source code if you're still not sure though. There's also a visual editor.
