When I try to load in the mod, Minecraft's Mod error screen pop's up saying that Origins++ requires the mod apoli. But in your Description, where you put the required mods to load up Origins++, apoli is not one of the mods included in the description. If Apoli really is needed to load up this mod, Please state this mod in your required mods section.

Thank you for your time. Have a nice day.

Hello! Apoli is one of the internal names for the Origins (Forge) mod, could you please check to see if you have it installed?
