Mobile run time generation Z rotation wrong

[vaskes]

Steps to reproduce:

1. Use Topdown_SciFi assets and DA_SciFi_K4 profile from starter kit. Dungeon theme SciFi_NoRoof.
2. Make a runtime dungeon map and compile for mobiles (Android ETC2 in my case)
3. Deploy on actual phone and try to play.
   Result: All walls messed and don't match the floor.

Why this happens: Topdown_SciFi assets have pivot point not in the centre of mass of mesh but in left- bottom corner. During buildtime and on a windows rotation correct and around pivot Z axis. On a mobiles during runtime generation wall rotates not around pivot axis, but center of mass of a wall mesh. With a prebuilt dungeons mobiles works fine.
