Be able to access the backpack inventory. To be able to unequip and use it.

Required informations (please complete the following information):

Greetings, I was able to get around this bug by changing the key to ";" or numpad 0
Hope that helps!

You need to remap backpack key bindings, because if something is mapped to the same key, one of them might not work.
In my game "Travellers Backpack" key is "N", and "Inmis" backpack key is "B".

The key 'g' is somehow bugged, try another key.
It is mentioned in #52

ok ty

now it works :))
