"Failed removing thing '[...]' from district at cells [...]" when expanding/shrinking stockpile zones

[ilyvion]

It doesn't happen every time, but I've gotten this exception randomly a few times now, so I figured I'd report it. I get it when I try to expand or shrink a stockpile zone. Here's an example exception text:

Root level exception in OnGUI(): System.InvalidOperationException: Failed removing thing 'VFEC_Toga1846' from district at cells '(156, 0, 124), (174, 0, 127), (154, 0, 123), (161, 0, 129), (175, 0, 133), (175, 0, 127), (177, 0, 133), (177, 0, 132), (177, 0, 131), (179, 0, 129), (179, 0, 130), (179, 0, 131), (179, 0, 132), (174, 0, 127), (161, 0, 129), (175, 0, 133), (175, 0, 127), (177, 0, 133), (177, 0, 132), (177, 0, 131)'

I've uploaded a log here: https://gist.github.com/HugsLibRecordKeeper/9f46ccc0cfd41e4032bf5b0ad0577030 The exception is the very last thing in the log, so you can just scroll down to the very bottom to see the full stacktrace.

Apart from preventing the expansion/contraction of the stockpile from happening, which is a bit frustrating, it otherwise doesn't seem to have any lasting negative effects on the game as far as I can tell.
