Save file won't load and crashes application

[arbitraryname]

Not sure if this is the right place to post, but I have one save file which crashes Simutrans when I try to load it. All other save files load fine. Previous save files of the same game load fine also, and I didn't do anything unusual when saving this latest version of the game. Would someone be able to have a look?

The save file can be found here https://drive.google.com/file/d/1bw2O4JzH16d7Y9UldOFAKnu25DkL_v8R/view?usp=sharing
I'm using simutrans version 122.0 and the latest version of Pak128.Britain

[Dwachs]

The file loads fine with current nightly. The pak128.Britain version on my computer might not be up-to-date, but no problems.

The crash was already fixed in r9700. However, valgrind still complained about uninitialized values when opening the save, this should be fixed now (r10295), too.

EDIT: Running the save in a local server causes a desync immediately after connection:

Seems like 2 ware_t packets take different routes on the client and on the server.

Cannot reproduce the desync :/

[ceeac]

I managed to reproduce it when starting the server with -pause and server_frames_per_step=1 and for some reason when frames_per_second=60 (frames_per_second=5 does not produce a desync).

[Dwachs]

With these settings I get desyncs as well.

[prissi]

Does frames_per_second=60 work with a normal savegame? Given the actual timer resolution, I wonder if these are accurate enough for network games. I think very few people used ever values higher than 25.

[ceeac]

Yes. In addition, starting the server without the -pause switch does not cause a desync.
