So, I've been playing the modpack recently, been having fun.
Until, I pressed a button (I have no idea which) and now I'm stuck in remote view.
This is a problem, as I have been using handcrafting for a few things, and my inventory contains several items that I wish to withdraw.

Note that I had previously been able to freely switch between remote view and being outside of it before.

I feel that this issue is separate to the already existing one about a similar problem, as that one states being in it and stuck in it from the start, as compared to my problem, which only happened in the middle of my game.

Hmm, you shouldn't have been able to switch to begin with, I'll have to try and safeguard that more.
All I can think off for your situation is seeing if there's a mod that lets you exit the hub.

I just finished making a mod that lets you walk freely onto your space platform, try it out if you can! (Test it in a new game before testing it in your own world)

I have same problem as maeep. But I decided just play further.
Later I stuck with more strange problem: my inventory was full of blueprints. I can't open my inventory and can't cancel my current blueprint.

Thanks maikuu for the mode. It resolve my problem.

I found the button, it's the enter key. Same issue. cant leave extended view. Temp fix by disabling the hotkey in settings
