How to remove item from underground? I cannot simply do it and I must use cut tool to do it. It's mess in my "underground world". I know I shouldn't abuse this mod/over use it, but I just want to play with it and I cannot, because it is too messy. I don't know if it is because of version, or because it is intended?

(what exactly happens is - progress bar when taking down is backing up to 0 every tick or so)

Also cut tool doesn't work too well with this mod. When I have some belts on navius and some belts in "underground world", they are overlaping and than I cut on it game crashes.

Could there be option to disable cut-paste compatibility?

How can I "normally" remove belts when underground?

As important note : I have mod that uses different worlds and might interfeer with my abilities on "another worlds" - space exploration. Perhaps this mod is preventing me from taking down stuff underground because .. some reasons?
I need to know if it is intended to work or not.

This is the fault of Space Exploration. It disables mining when in the "god controller" mode, because it uses that mode for the satellite uplink. Unfortunately there isn't a way to disable it just for the satellite uplink. You can hack Space Exploration to turn that "feature" off, if you like, by editing data-final-fixes.lua in the mod zip for SE.

where do I edit it and can you make a seprate mod so we don't need to mess around in the files?

Look for a line mentioning “god controller” and “mining speed,” and delete it.

Thanks this helped. For those who will face this problem too: comment or remove this lines from data-final-fixes.lua in the Space Exploration mod zip (located at %appdata%\Factorio\mods). I am using space-exploration_0.1.149.zip

data.raw["god-controller"]["default"].item_pickup_distance = 0
data.raw["god-controller"]["default"].loot_pickup_distance = 0
data.raw["god-controller"]["default"].mining_speed = 0.0000001
data.raw["god-controller"]["default"].movement_speed = 1

you don't have to delete anything, just change
data.raw["god-controller"]["default"].mining_speed = 0.0000001

to

data.raw["god-controller"]["default"].mining_speed = 1.0000000

that's the only thing needing to change
