When I create a pile of 4 logs, the character spends 2 ropes to create it, but after I untie it, the character gets 2 extra ropes from somewhere. I attach video material from YT

as per title, setting the population to 0 in the sandbox doesn't work. it's very handy to test new stuff without zombies around, it does save a lot of time and possible death for not knowing how to operate stuff
