When I was looking into downloading this mod, I seen A LOT of negative posts here saying "it doesn't work" or "dragons aren't spawning" ect...
So I installed the latest version of Forge 1.16.4 v.35.1.4 and installed the appropriate mods located on curseforge and citadel and is deobf file.
(FYI Dev's, you may want to update the links to citadel on the curseforge as it takes you to the 1.16.1 version of them. clicking description, and then back to files brings up the correct version needed for launching.)
And after installing all the necessary components i got an crash report on loading up with the deobf installed saying "Mod loading error has occurred" and "Citadel has class loading errors"
After removing the deobj file, the mod seemed to work load just fine, and I checked some of the usual complaints people had about dragons not spawning ect... but sure enough after looking in the correct biomes, viola!
Also found an ice dragon roaming around on surface too.
I can also confirm that many of the structures were also generating.
After looking into some of the complaints people had about issue, I saw some people had MULTIPLE mods installed in their list (obviously this mod isnt compatible with all of them.) and some were even 1.16.2 and beta versions of mods.
So in conclusion, I just wanted to help out the community and say that this mod is in fact working 100%! If you are having issues with your game or spawning, make sure you remove your mods and try installing them again one at a time to see if there are any incompatibilities.
I hope this helps anyone looking to install this mod.
GREAT WORK ON THE MOD DEVS! <3 love the work!
