Confirmed with 1.11.0. Haven't bisected, but a quick test of 1.11.0 Beta 2 didn't trigger this issue.

e56d2c6 has the crash.
The commit parent of the above one i.e. 3a4a15c does not have the crash when compiling locally with cmake ..; make -j 8.

I'm currently unable to test this myself, but https://gist.github.com/michicc/1c6f8f0b5322c2cb8f0acc908d6b755a might possibly fix this issue.

When a crash occurs during a save operation, the file can not be used to load a game.

Overwriting an existing save file always works.

@michicc on master branch with your patch I have been unable to reproduce the crash and it is now working as expected. Without the patch the crash occurs.

@amf0336 I can confirm the behaviour that you are seeing too. With the above patch the issue goes away, as I've been able to load any of the files I've saved.

@smsm1 If it's not too much a bother, could you try the patch with both waitUntilDone:NO and waitUntilDone:YES? Principally, YES would be more correct, but I'm worried about it causing a thread stall.

I'm going to prepare a pull request tomorrow for this.

When I use waitUntilDone:YES, when clicking save I get a beachball and openttd is completely unresponsive.

Thanks, then NO it is.

I'm experiencing this bug, latest version, same message, but ONLY if I save by hitting enter in the save dialog

Can you please create a new bug-report, with the crash log attached? It is possible, although the issues look alike, that they aren't. With a fresh bug-report and crash log we can look into that :)

Thank you!
