Rotated WMO objects in map exports

[BSarmady]

This screenshot is taken from blender (after importing map with all objects. It is from human start area. The cave that is seen in the screenshot should have its opening about the area that is shown by arrow. Apparently the cave is rotated about 90 degrees. It seems that this issue is only happening with WMO objects.

Next screenshot belongs to menethil docks, which seems to be rotated 180 degrees.

I probably could fix this issue if I could figure out how many degrees I need to rotate wmo objects, but it doesn't seem to be same in all instances.

There are more wmo objects with this issue but I guess two examples would be enough.

Also in another issue, I can see some areas of the land texture is red (mostly in sea area under zero level). I don't remember seeing red in those areas in the game, but I cannot confirm since I don't have access to game at the moment.
