I have just played again and noted that some previous problems still persist, and a few more seem to have cropped up:
Portals: patch note says that these do not activate until someone goes inside, unfortunately, this also seems to include random creatures walking by.
As I read the patch notes on this matter:
Patch Notes 1.4 (should go live on 15th of Nov.)
• The "pocket" worlds were generally redesigned, so they are more playable and valuable. Also added some super-monster lairs with super-loot inside. The monster in such pocket worlds don't spawn until someone come inside, but after they do they actively seek the portals to come to Ardania and Rampage there a bit.
"in such pocket worlds with super-monster lairs" - to me that means only the worlds containing super-monster lairs..
But my interpretation could be wrong..
