Currently, the GMs consider it "bug abusing" when somebody makes use of the feature "building shadow". Note that a character who is in the shadows of a building cannot be targetted nor seen, not even by characters that are in the shadows themselves.
Many might know I give a smile on realism and I am one of the last who promotes to take something out the game that offers roleplay options. Shady characters, hiding in the shadows of buildings, stepping out of them and whispering something like "Shh! Want to buy an O?", that's something I like to see in this game.
So, what to do? First, I'd block all building shadows of two story buildings (problems seems not to be present for one story buildings) with stone, hedges, whatever. This way, running in the building shadows get prevented and the GMs have a reason less to ban players
One request: In case anybody replies to this, don't start unrelated bitchin' about certain players (ab)using building shadows.
Effort: Map changes (trivial), map update
