It appears the modification for custom ranks left some log() output active which.. is spamming the log (on each kill? not sure) with this:

Script @heroturrets/prototypes/scripts/turrets.lua:159: {
50,
250,
500,
5000
}

...possibly because the cache in the function isn't implemented correctly? the first line:

if local_get_kill_table ~= nil then return local_get_kill_table end

should probably use "kill_table" instead, since that's the variable name used below?

good catch, the log out put was left in intentionally but not the repeat calls, will fix

funny will always be nil as a local is calling itself. ups fix too good work

Thanks for the quick fix, I can confirm it is only logging once now :)
