Editor crashes when I try to build a new element on the map. But I did build an entire town, a lot of elements. If you are truing to build elaborate maps it will crash.
I am level 15 currently. If you know what you are doing and you have a pinch of luck (making potions), you can play (for FREE) for a few hovers every day. I have a life and a job, a few hovers per day is quite enough. The game is very playable. But those SAIL gems and stuff like that is VERY annoying. I am a fan of HMMO, influence is obvious, and I LOVE THIS GAME. I don't mind to wait for stamina bar to recharge. It takes just 1 hover to recharge. GG :)
