Known Errors: Bugfix provided by Battle Bunny:#
- The game crashes frequently. Most of the errors are due to JPs being one or two bytes off their correct destination. The most significant error was the machine stack overflow, caused by indirect recursive sub-routine calls, which would cause the program to crash if Crusoe did a lot of moving back & forth between map sections and had to use his "Elyxr" frequently. There were some minor errors in the keyboard checking, command handler search and message display. Also the LLL option to load a saved game messed up the stack and the QQQ/TIUQ option to restart didn't work properly (although that was due to the stack being messed up by other things). Fixed using the following patch:#
