Hello, the mod is now available on mod.io and through the mod downloader. In the future refrain from using 0ad>=0.28.0 as it causes issues (You cannot guarantee what will happen in the future)
@DesertRose I had the same issue. I think I fixed it by doing a git lfs pull as recommended by @Stan`, but it would only work doing so from my own fork. Sync your main branch's fork from the web UI, then use it to re-base any local branches.
