Thanks for your report. The vocab 0 file in this game seems to be damaged, or at least it does not appear to contain any actual vocabulary. The game does not appear to need this information to run, so I have added an early escape from parsing in commit 444b11b1bb7cc01cc26cdd61247eda536c2cb7d5 which should allow the game to load and run again. It is very possible that this is not a complete/proper fix, but it makes things no worse off than they were before (when the vocab parser would have just continued to read into adjacent memory). This fix will be available in daily builds 1.10.0git-3278 and higher.
