If you copied any Windows stuff from the update into your Linux game folder you probable bork your NWjs. Easy to fix.
(1) Download the early Linux v.51113 of TGO from first page of this thread.
(2) Move all files outside of your game's www folder, on your PC, somewhere else temp in case you need them later leaving only your own www folder behind.
(3) Copy all of the files in the v.51113 folder OUTSIDE the v.511113 www folder into you own game folder and finished!
Should have working Linux game again.
