Yesterday I had a score of 1800 on the first map and now there is no more score. How could it be that this score was deleted? Furthermore, my scripts/modules were also deleted (I luckily saved them locally). Does it depend on cookies or something; what happened?
In Simulation Room, your modules and scores are stored in browser localStorage. You may be using another browser or another anonymous browser session.
I had the same thing when I went to http://www.screeps.com instead of http://screeps.com, notice the www part. these 2 store your data in different locations.
