according to the posts it seems to crash on many (all ?) wine configuration, both linux & mac. I understand the point of dev, but please keep in mind neverwinter was working fine on wine before mod4. And that brought to neverwinter many players who wouldn't have come otherwise. Wine & logs give quite no information,…
This is a lazy answer. They do now the changes done on mod4 and they could at least give some clues. Wine give very few information on that crash, finding the cause just by ourselves will be painfull.
the linux crash problem was reported on preview http://nw-forum.perfectworld.com/showthread.php?713951-Mod-4-crashes-on-Linux-and-Mac Sadly, it's not fixed and now it also appear on live.... Gonna start a separate thread for that one, it's not the same problem than the one described by the 1st poster.
Same problem for me as well. Game run smoothly on live server but on preview getting a crash after clicling on launcher since mod 4 came out. Crash reported in ticket 33720101 I like this game and i'll be very disapointed if I have to quit in mod4. Please don't let us down !
