I was using

   var roomContainers = Game.rooms[creep.room.name].find(FIND_MY_STRUCTURES, { filter: (structure) => { return ((structure.structureType == STRUCTURE_CONTAINER)) } });

                    console.log("Containers: "+ roomContainers.length);

Apparently Containers arent in the MY.

Once I swapped to FIND_STRUCTURES it worked

Hello,

   Just started screeps and hoping to work at for awhile. I put my current screeps on my github http://www.github.com/MrC0de  and I am hoping folks can advise me on any topics they see as relevant. I am becoming increasingly concerned over the cpu spikes I see that I am pretty sure are my fault.

    I'm basically collecting advice to ponder while optimizing later, looking for things to consider, feel free to bash my scripts I welcome your constructive criticism.
