Just realised that most chunks aren't loaded either, when this is fixed I'd love an ability to reload chunks in bedrock as you can in Java.
This only happens when loading the nether, never has happened when going back, which is the opposite of what I expect as I have nothing yet built in my nether other than a correctly placed portal
This is a bug I have also been getting! I also use this texture pack, it does not happen all the time , it seems to be a rendering bug. The game loads perfectly fine but It doesn't show anything for another 30 seconds, meaning that the zombie pigmen who I hit back into the nether portal when he came into my base killed me.
Just tested without the texture / resource pack , its not the resource packs cause, its just a bug that happens with Minecraft Bedrock rn. Please fix when possible
