Summary0000799: Unavoidable crashes after upgrading Cavaliers at Stables
DescriptionFirst it looked like two unrelated crashes: one with game save and another with entering Crypt. But after testing and re-testing to narrow down the cause of both crashes, I realized they're both related to previously visiting Stables with Cavaliers in my army (which were getting the free upgrade).

To easily reproduce, take Rion in the saved game attached (1st archive) and go to the Stables (if you don't do that first, you'll be able to save / enter Crypt / etc with no problem). After that, try to either save, or visit the Crypt to the left:

- If you try to save, you'll get a crash when returning to the Adventure Map, and if you check the 'games' folder, only 2 out of 3 files were created (as attached). Crashdump created automatically.

- If you try to visit the Crypt, the game freezes just before entering. You need to type in 'crash' in the Console to create a crashdump.

Should be easily reproducible, but I'm attaching all files just in case.

EDIT: The game simply becomes unplayable with that hero after the Stables upgrade. I've tried other actions with it otherwise, including an attempt to simply dismiss the Champions, but the game always crashes. I guess at some level the Stables upgrade is not correctly registered, and whatever actions involving what use to be the Cavaliers, lead to a crash.

Fixed in r2354.
Issue was indeed specific only for stables performing upgrade, creating a corrupted stack on server.

I had another crash when visiting Stables with Cavaliers in my army. I thought it's the same as this known bug (and forgot it was fixed), so I didn't take screenshots. But then I thought of double checking... So I found it as Resolved and went back to see if it's reproducible. Unfortunately I couldn't reproduce it anymore. You can check if the crash dump file I attached here tells you something - if not, I'll keep an eye on it, and if it happens again, I'll create a separate report, with proper screenshots & everything.
