most players cannot see movement of monsters

My wife and I both use Debian on the client end.  A house guest just connected from a Mac, and when he scares birds they fly away.  I'll attach the most recent log.  He was the last one to connect.

server_log.txt

Just in case it isn't clear from above:  This problem seems to affect all monsters for the affected player.  The butterfly and bird are just examples that were easy to get details from.

I logged in to my account on my wife's computer.  When I launched Don't Starve and joined my server, I could observe the problem, at least with birds.

On my wife's computer, we upgraded from Debian 8 to 9, purged steam and dontstarvetogether, removed ~/.steam and ~/.klei, and then reinstalled steam and dontstarvetogether.  Now when she connects to the server she sees birds and butterflies move, and can interact normally.

There is no longer a problem on systems I can check in the immediate future.  It seems like the problem was resolved by changes on the client end, so it doesn't seem to me like this is a bug, at least in the current server or client.  Since the problem remained after the OS upgrade, I suspect the problem was caused by old data files, either incompatible with the current version of the game, or just corrupted somehow.

 

I don't see a "close" button, so I won't worry about that.  I'll post again if I can find out anything about the other problematic clients.  Right now, looks good.
