Another small update:
V3 Build 15a
+Changed - Bots shouldn't make bots-towers on ladders anymore (they test all the ladder right now - not only if the current WP is used by another bot - like it was before).
+Changed - the creation of the visibility table doesn't lag the server anymore.
+Fixed - the WP editor - now You should more easy and more precisly point the WP You want to manually make the path connection.
@Ancient - please report me if these second and third ones really work better now.
