as seen in 0.59 and continued with 0.60 loot-hoarding in barrels and tents prevents the respawn of those items on private servers.
e.g. when hoarders pile up certain guns, they do not respawn anymore to no-one.
which causes the loot economy to get broken.
all hoarded items get excluded from respawn, after a certain number has been reached.

• lucky for the hoarders - completely useless for people who join these servers for the first time.

all of this already happened with 0.59. but with 0.60 the speed of exclusion seems to be accelerated. what took 0.59 almost a month or two, 0.60 achieved in less than two weeks.
some of the private servers already become unplayable (because of excluded loot like backpacks, mags or guns) for new players.
this is not a feeling. i do not say: "i think this happens". this is real and kills all balance on private servers.
