I would like to ask about the CPU cost of the new spawnCreep function.

By now, I am using this code snippet from the api documentation with ("low CPU" + 0.2 CPU) cost.

if(spawn.canCreateCreep(body, name) == OK) {
    spawn.createCreep(body, name);
}

If I replace this by

if(spawn.spawnCreep(body, name, { dryRun: true }) == OK) {
    spawn.spawnCreep(body, name);
}

am I right the CPU-costs would be charged 2*0.2CPU, since the function spawnCreep returns OK two times?

Personally, I like the idea of immortal containers. One of mine had a negative decay time of -15 as seen in the screenshot (if the upload works...)

I don't know, what happened, but it occured on shard 0 in room W35S88 at about tick 21275400. There is no replay-Link I can post, because for some reasons the replay returns "no data" for me.
