Sometimes crates fall through the map, this is an issue that affects vanilla helicopter also for some time, nothing to do with my plugin. If you see messages in the console like this:
this means the crates have fallen through the map and are destroyed.
Heli crate spawn is not handled by my plugin, my plugin simply tells the game how many crates the Heli should drop. If there is an issue, it can’t be with my plugin because when each Heli spawns it is told how many crates to drop when destroyed. Check your config and make sure you do t have zero crates set on some Helis. Otherwise I have no answers for you.
im currently out of the country on holiday so I won’t be looking at issues until I return in a few days.
