i wanted to play the ftb ocean block modpack so i tried it but it was really laggy that i couldn't play it so i downloaded "Rubidium" for performance and well.. it buffed my fps a lot and it's actually playable now but the problem here is that the world is buggy and most of the blocks in the world is just invisible even tho i can move and break things with stable performance, so i'd love to know the reason of what's happeining here Here's the "debug.log" from the modpack folder: https://gist.github.com/yousv/1bb24ba7d9c48dfe64d3a2588614f15e
