dcs_check_list_arguments: Found 2 datum list arguments with similar contents for /datum/element/give_turf_traits. Contents: ["turf_ignore_slowdown","turf_ignore_slippery","immerse_stopped"]. at code/modules/unit_tests/dcs_check_list_arguments.dm:51
dcs_check_list_arguments: Ensure that each list is static or cached. string_list() (as well as similar procs) is your friend here.
