Does this fix the issue? If a shared group window is opened, then the list size is reduced from 2+ to none, it will still crash, no? |
Hmm, I'll check that later tonight. However, if this was the case, then this bug would have been in OpenTTD for much longer than my PR for grouping by shared orders (and hence surprising that it was only discovered now). |
I've just tested and it no longer crashes: In the linked savegame, I bought a new vehicle and cloned the orders of vehicle 289 to it, then sold all vehicles in the depot (i.e. both of them). The shared orders window disappears as expected; no crashes. I believe the code that deletes the shared order window when there is only one vehicle left is this: Lines 2790 to 2793 in 799eb31 Presumably selling all vehicles in the depot will delete vehicles one-by-one, which is probably why it works. |

Motivation / Problem
Fixes #8922 - shared order list could have only one vehicle, which leads to a crash later when that vehicle is deleted.
Description
When viewing by shared order groups, if a vehicle is not shared, don't open the shared order list (of just a single vehicle). Instead, open the vehicle window.
Limitations
None
