--- Comment #8 from Vexorian vexorian@gmail.com --- Testing in 1.9.3:
- Running Heroes of the storm 32 bits client, There are freezes between 0 and 30 seconds after the match begins. - Running the 64 bits client, there are crashes and they seem to happen in a similar way to the freezes in 32 bits client.
All game modes have the same issue. It's easiest to test in the Shop's try mode. Testing in a real game mode makes the game crash and then when you reload the game it asks you to rejoin, rejoin reproduces the crash, this issue will persist for a while until the server dumps your ongoing match. Don't test in Quick Match as it will cause you a leaver penalty.
Regarding reproducing the bug: There is a separate issue that has been around before the most recent patch and it is a seemingly random crash during a match's loading screen. This can also be reproduced in try mode. In my case, if you don't get this loading screen crash in the first match of a game sesion, it will not happen again. If the loading screen crash happens during load time, you can rejoin the game and the crash will not necessary repeat. (This was before the new crash that happens all the time and when the match is happening).
