anyone kno a plugin that i can use to change the timers on the locked crates also..a plugin that can can use to add more locked crates to the cargo ship and chinook?

Add hackablelockedcrate.requiredhackseconds 900 to your server.cfg. Change 900 to whatever you want. readcfg for it to take effect.

I dunno about more locked crates, but you could add more slots inside the loot box with https://umod.org/plugins/better-loot

I don't think there is any plugin for adding more crates to cargo ship and chinook.
