Bug in observer mode

Long BGH 2v2v2v2 game. Around 50 minute game desynchronized for me (I was observer). Units started to do weird things etc. Coudnt whipser to oher players (or they didnt respond to me).
I exited that game and saved replay (saving operation took like 20 seconds). Then I started replay - eveyrthing looked fine. Except there was no messages in chat.

Is there an ORL file next to the replay, with the same name? If so, could you send the ORL and the replay file to ramius.forum@blizzard.com?

I sent this file using wetransfer dot com
file is password protected, so there is a second email from me with password
