I've seen this happen a lot: I've been playing a game for more than sixty game years, then when I try to load it Simutrans crashes. I'm using the Simutrans nightly 102.3-3764 with openpak128 build 1044.
Here's the relevant error output to the console:
Calculating textures ...done
FATAL ERROR: fabrik_t::rdwr()
no besch for Sandquarry
It happens both when I use the same version I used to save it and when I upgrade to a later version.
Within the pak128/ directory that contains openpak128, the sand quarry file does exist:
% find -iname '*quarr*'
./factory.Stonequarry.pak
./factory.sand_quarry_dd.pak
I'm not too concerned about recovering this game, but is there a way to prevent this from happening in the future? I appreciate any help.
The factory factory.sand_quarry_dd.pak is called 'sand_quarry_dd' internally, not 'Sandquarry'. Apparently the pak-file for Sandquarry is missing.
Did you change your pakset recently? I mean, is the pakset that you use to load the game the same as when you saved the game?
The old sand quarry has been removed. It should be part of the compatibility pack. You'll have to add it manually...
This game was started with the new openpak128, though. Why would a game started with this openpak128 version want the old Sandquarry?
No idea. Ty adding it and look for it?
It's not part of the compatibility set on the pak128 site, but I found an old install of 0.99.14 that has it. After copying it, it complained about a few other missing items, so I did a cp -n of the pak128 0.99.14. Now Simutrans segfaults when I load the game:

Hmm. Looks like I should update the compatibility pack again...
A few couple missing: sandquarry and electronics factory. I'm not sure what to make of the segfault, though.
...until the compatibility pak is finished, you can look some older version for the file
"factories-unfree.all.pak".
When you add that one, it should work (it is then no more open-source, anyway).
