What do flame particles around the map mean?
Development worlds. /20char
If I am getting this right, do you mean a red circle of flames around a flag or dot on the campaign map itself? Like Backwoods Forest?
If so, it would signify a level for multiplayer I believe. Like what @ant describes here:
Otherwise if you mean like on the Game Development 1 Campaign “World” I do not get to see any flames. If you can screen shot it perhaps I could comment further.
And purple circle ?
Adventurer levels. Levels that are for testing before official release.
