Example: So just across from the mid west islands on the nw side of the ascension cave we have all kept crashing writhing the same region. No mods no alterations nothing non vanilla but keep getting the same error: assertion failed: (index >= 0) & (index <arrayNum) [file:g:\svn_ark\engine\source\runtime\core\public\containers\array.h] [line:572] array index out of bounds : 1 from an array of size 1

{update/edit}
So we figured out it was due to the server files not being up to date with the mod so all reagions that were changed but not updated were areas that caused the game to crash as it was lacking the proper assets.
