Saved game load failures - best way to debug?

[jonbaer]

First time I have gotten this - I'd rather help w/ this bug than complain about it (since this is an SVN copy) - I have to assume there are unit tests for load/save but is it worth tracking this down when it happens?

Had SVN been updated since you saved the game? (Just to rule out the obvious.)

[jonbaer]

No they were recent games w/ no updates, I just unziped the .0adsave to compare the engine_version info "0.0.21" (since I think you are suppose to get a GUI box asking for loading previous versions - correct?) ... 

I did do a quick save game and load and it worked fine, guessing since these were longer matches it was something else.  Going to place a few console.logs inside of loadGame() or at least something that tells me what element failed to deserialize.

Alpha 21 engine version is not enough, it must be from the exact same revision. There should be a timestamp in the metadata inside the zipfile, that should give a hint on which revision was used.

If I put some more logging in CComponentManager::DeserializeState it shows that the error occurs while handling Pathfinder component.

If I force PSERROR_Deserialize to return true + load anyway this is what I ended up with @ crash time (not sure if any of this helps) ...

To me it sounds like you saved before #4277 and tried to load with a later revision.

Well after accidentally deleting the bad .0adsave file(s) + playing a few more long length saved games off latest SVN I wasn't able to reproduce so your assumption is probably correct.  I also just realized I may have (or did) play w/ pyrogenesis -writeableRoot in the same development location on my hard drive.
