Summary0022595: NullReferenceException with a spam of errors in the log
DescriptionThe error in "errors_spam.txt" is spammed in the log filling it up (hundreds of lines per second), so I lost the initial logging. I retrieved the Engine Error which I assume is correlated to the spam. I got also another exception which is similar to the one above (both in the "exceptions.txt" file). All this is causing my game to run as low as 30% performance on 1x speed, like it's accumulating lag, because it doesn't immediately slow down, but as time passes.

Thanks!

* Fixed an exception in the claiming code for neutral entities that could happen and then spam the log endlessly.

Thanks!

* Fixed a really rare and strange error that could sometimes happen in FramePartTimings. This happened to Chris periodically for the last year, but it had never been seen "in the wild"" until Daniexpert ran into it. We thought it was just related to the dev environment somehow, but it seems to be a cross-threading thing that can rarely happen on startup if things go just wrongly. The game itself will run terribly and spam the world if this happens, so making it gracefully recover is a good thing.
