Hope you come back later, Steve. Thanks for the SWC-organization and our other encounters in Screeps!

I have seen a bug where if you sit on shard1/E1N1 and change the url to shard2/E1N1; then use the minimap to look at a nearby room you end up on shard1 again.

Not sure if that has caused your problem, but just in case it is related.

That explains it, I'm not checking if I'm the owner when I run foreach on all PCs in Game.powerCreeps.

@artch

I'll try to setup some tests to check that, tell me if there's anything else you would like me to try to capture about the tick or environment.

I saw it maybe two-three times in total last night, without any obvious system.

Can confirm this error, was just sitting and debugging a similar case.

I'm extending prototypes, and this gives a similar error of memory is undefined at infrequent intervals:

PowerCreep.prototype.getHomeroom = function (): string {
    return this.memory.homeroom;
}

As long as the closest wall is not at max HP, you will have a structure for closestDamagedStructure. The last if (except attack) will "overwrite" your earlier repairs.

This will probably fix it (using else if):

    if (closestDamagedWall) {
        tower.repair(closestDamagedWall);
    }
    else if (closestDamagedRampart) {
        tower.repair(closestDamagedRampart);
    }
    else if (closestDamagedStructure) {
        tower.repair(closestDamagedStructure)
    }

I agree, and I've shared my idea of how it can be solved in the thread "A different shard" (https://screeps.com/forum/topic/2273/a-different-shard/)

Basic idea: When making shard4, use the 4x4 or 6x6 sectors in the middle for this purpose. Make the area restricted with natural walls and disallow spawning in the rooms. Increase the number/values of sources, and make it accessible only by a new type of portal. (read thread for full context)

Agree as well. I'm not saying it's impossible. However, what is the difference between a player that has respawned, where the ramparts go public, and a player that has let their sub run out, gone zombie, etc. and lost all control of their rooms? The potential payoff (or lack thereof) in either situation is the same. Is slugging through old empire ramparts at shard0 tick times just to claim a room seen as a rewarding challenge? Are any players actually migrating to shard0 to do so? I haven't really investigated the other shards, I assumed that this really is not as much of a common situation elsewhere. Completely open to changing my mind, so I'd love to hear more thoughts.

That room is a single example. There are more with little to no payoff, they only serve to hamper expansion. Even in the case of that room, not really... unless you were starving for the Z. A storage full of unreacted minerals would be a payday for a newer player, but they more than likely don't have the means to pull down a 300M rampart in a timely fashion to make that worthwhile.

Agreed, but I'm not sure offhand that I've seen a recent case of a completely walled off room with HP high enough to cause as much trouble. Completely walled off rooms tend to be a new player single room tactic, not a larger empire tactic.
