Neverwinter Nights 2 Complete from GOG.com loads to the menu properly but
crashes when I load a previously saved game or start a new campaign.
The game version is 1.23.1765.

Used to work until

ntdll: Define heap block's BLOCK_FLAG_LFH as 0x80.

Reverting the patch on top of current git fixes the problem for me.

No demo version is available.
