Summary0026389: MP Errors 2.803
DescriptionResults of a 20 minutes quick session
My client was playing Necro sidekick and the host was human empire.

Whenever the human empire would claim a new flagship/Ark, it would vanish from the client. Reconnecting made the flagships visible again

On the client, I saw the following errors:

This is the "two" canary code, which should be fixed (and there were a series of errors after that which were all just downstream cascades from this:

* Fixed an error that was causing a multiplayer desync if the unit died on a client right before it tried to deserialize a unit order out of its list of orders.

* Entity orders are now structs rather than classes, and no longer need to be pooled. This is a notable boost in speed, particularly because these are so extremely frequently used and replaced. This should smooth out performance on MP clients in particular, but it also makes loading a save slightly faster. This should also reduce the surface area for further MP bugs from this section.

The host error:

* Fixed an exception that could happen in intel generation, and also made the error handling in that section more robust.

I got what I can in the current version. The # hash errors are incredibly strange, I don't see how they could be happening without another canary error directly prior to them based on how I'm doing the canaries. It's... perplexing.

I'll try to recreate with your changes soon. Thanks for the prompt attention!
