resistance quest (filling water bottle).

So i don't understand this quest. Sometimes it let me enter but sometimes it don't, and the water alway go down when i fill it. Help me plz?

Edit: managed to find how. Close the thread plz.

I'm also trying to figure this out, and would love it if someone would help explain what to do.

If you can't enter, that means someone is already inside and you need to find an empty channel. Just drop 10 water bottles, 1 at a time, on the water tank.

I hate when someone posts a question, finds the answer and instead of posting the solution they simply request that the mods delete their posts.

Specially irritating when it's a thread you found through a Google search.
