Not sure if this is where you ask questions like this, but here goes. Whenever I download a campaign, I save the missions to files, and I can then play them in the FrozenThrone file in Custom Game. The Heroes and Items seem to carry over, so the campaigns are working in that regard. However all the custom models don't seem to work, and I cannot train or interact with any units that use these. Sometimes they are also replaced with regular units that use the same files for some reason, idk if that helps. Do I need to download all the models separately?
