I play in pc steam. When i was walking over de hose, next to the sandbox, i don´t know why or how, i´ve went inside the hose. The exactly site is close the mark of burgl chip down the hose. I toured all the hose on two sides and there´s no way to go out… i jumped to try to exit and all i can do, i tried all in my hands but it`s imposible to go out… i dont want to lose all my stuff pleeeease help! I tried to die and go for my loot but i can´t catch the bag through the hose.

There is a retrieve backpack feature in the options menu you can use to retrieve your now stuck backpack.
