Since this is happening on the Civ server, posted only here. Using the commands "/wd add claim" and "/wd dl" the server returns the message for an internal server error. This does not occur when using "/wd add", with or without radius, and occurs after the "Checking for claims..." message is given for the dl command.
Seems unlikely that will help, as it is apparently a server issue, although I can try it. Edit: Force Update did not help.
I think we've pinned it down to it not being installed with the pack when you download it. Will need someone with access to the server which provides that data. @Slind @SirWill After its been updated to add the mod, you will need to force update the pack and choose to download the mod when prompted.
this sounds like sub claims which is currently broken with the world downloader mod. might want to try to recreate the claim.
Not fixed for me. Added mod, did force update. Mod was not listed in ForceUpdate list, but is listed in mod list accessible from main menu. I get this error, in a test claim that I just created with no subdivisions. Tried in SkyFactory, works as intended.
