Pre-defined maps in scenarios

[dita]

Just a quick question(s).

Is it seen as acceptable to use the pre-made maps for scenarios? I wouldn`t like to use somebody elses map only for them not to like me using it

One other question, looking at one of the maps, there is a refinery. I cannot seem to find the icons used for the refinery. I can see the large container icons, but not the pipe work, which I can see on the map.

Thanks in advance
