I’m having the same issue, except when I add the City Pack, it also adds another texture pack called ‘PureBDcraft 128x v1.7.0’, which I never even purchased. If I remove files for PureBD, and leave the City Pack, then it loads just the default Minecraft textures. But every time I restart it’s adding the PureBD pack alongside City. City pack works fine in locally save worlds, it’s only realms that have this issue.
This issue has been marked as resolved yet it’s still not working for me!
