So, whenever I try to enter the '1000 Blocks' mod, it says 'Loading Resource Packs' and stays like that. Usually, my other Marketplace packs go to 'Loading Resource Packs' for not even 5 seconds!
And since you can't refund packs, that's, maybe, 830 Minecoins gone. It looked fun too...

Steps to Reproduce

1 Enter the 1000 blocks pack
2 Watch as the infinite loading screen appears

Expected Results: It loads quickly like other mods.
Observed Results: It takes a very long time. I haven't ever seen it load fully!

Hope I did good on this bug report! 😀
