For fast iterations just use a local server, you shouldn't have those problems then.
It is far better anyway to only push "stable" versions to the server anyway.
I think the server just reserves CPU, in a somewhat odd way by idling it.
I can use any given heavy task even if the usage is up in the 90% the server just scales down. (and right back up once the task is done)
I just don't understand why it is doing that and unable to give resources back.
Could that be a effect of the IVMs?
That brings me to an idea,
try to build up artificial garbage over some ticks and then delete it.
It would be interesting to see if that has any effect.
This consistently happens to me as well, with both the sign badge and the owner badge. Moving from a owned/signed room to another without hovering an unowned/unsigned room will not update related badge.
It's a little confusing at first, but yeah, it isn't much trouble.
Yes, the same would happen when a tunnel disappears when some creep is staying there, it may find itself in a blocked location, and its tombstone will also be inaccessible. It feels consistent and intended behavior.
