I've been replaying JA2 with the 1.13 mod for the first time in some years, having a blast but I'm also running into some issues that I hope someone can help me clear up.

Most important issue is this Runtime Error which is rendering the game unplayable, literally. Once it occurs, no matter how many saves back I go, it occurs, on saves that I've loaded with no issue a day before. Even starting a new game encounters the issue, requiring a full uninstall and reinstall of all game files

The error message is as follows:

Runtime Error
Press (esc) to exit

File: D:\a\source\source\ext\VFS\src\Core\vfs_file_rail.cpp
Line: 106
Function: vfs::COpenWriteFile::COpenWriteFile
File "FortificationPlan\D2.txt" could not be opened for writing

I have the game installed outside of the program files folder(s) and have no idea why it's even mentioning D: since to the best of my knowledge everything is installed to the folder I made on my desktop for games.

A less problematic problem is a constant ini error on the title screen that states the values for enemie and creatures in tactical, and number of hireable mercs dont match the values in ja2options.ini

If anyone can shed some light on these issues, particularly that 1st one, I would heavily appreciate it.

Thanks

The main suggestion I can give you is try to play the game in Windowed mode, I believe it was Alt+Enter. Often my runtime errors happened due to the screen resolution problem with using modern computers and, or a projector like my television set. Good luck soldier. One more option is clearing up space on the drives

Thanks for the response, I actually found a workaround earlier today that let me keep my save game, so that's great and I can try the windowed mode to see if it stops the error from occurring again.

For anyone that may, or may have, encounter(ed) the issue themselves, you can retain your save game by copying it out of its folder then reinstalling the 1.13 mod and copying your save back to the relevant folder.
