Game Crashes When AI is Defeated in Campaign

[Tealdragon204]

Can't pass the third mission for humans in the campaign because the game crashes once I destroy the town hall. I am using the GOG version of the game

I assume you are on Windows? If you can share stdout.txt and stderr.text and any crash.dmp file in the stratagus folder that you might have, that would help

[Tealdragon204]

Windows, no files like that in the installer version. Tried portable, glitch doesn't seem to occur in portable and is exclusive to the installer which didn't have any of those files

The installer version stores such files in %AppData%/Stratagus or Documents/Stratagus. Could you check?

stderr.txt
stdout.txt

Should be all the files. This time it happened on the Portable version but much later on into the game

Thanks, the crash.dmp helped. Just posting here the data for reference:

I'm not actively developing on Stratagus atm, maybe @Jarod42 has an idea.

[Tealdragon204]

Thanks! Would greatly appreciate it. I remember my dad playing this game as a kid and wanted to try it but I found the vanilla version to clunky and was having a blast with this mod until the crash. Would love to see it in working order

@Tealdragon204 the way to get past that is to cheat into the next level. In any mission, press return, type "corwin of amber" and hit return. this enables cheats. then again press return, type "human4" and hit return again. This way you'll unlock the 4th human mission in the selection screen

Attempt to read from address 00000030

The source line is const unsigned int t = AiPlayer->UnitTypeRequests[i].Type->Slot;. The offset we're reading from NULL is 0x30. The UnitTypeRequests is later in the PlayerAi class, so I don't think AiPlayer is NULL here. AiRequestType seems too small to have such an offset. So we get to the Type field that we're reading Slot from. Slot seems from the source like it could end up at 0x30 offset, so my best guess is we're dealing with a request that has a null type for some reason. This line looks a bit dodgy: https://github.com/Wargus/stratagus/blob/96ba028dfdc7ef8ba72bd161c5fd9a9ced45562a/src/ai/script_ai.cpp#L908C48-L908C48 type was not NULL before, but could it become NULL here?

Just want to add that I also have this issue, except with the Orc campaign mission 3, extracted from the actual CD, with the portable stable release. Here are my files:
crash.dmp
stderr.txt
stdout.txt
