It s a bug...they made post "known issues" ..i found issue, and reprted.. Dont know what are the priorities...Thought it plays like even, but if there are invisible lies..thats ok. No one can use it

p.s : This at least shows that remaking original UEL shouldnt be a problem, just need to make those lines visible, terrain already acts like uneven.. In fact uneven mode is older than even :)
