My test project started to behave strangely, and that's what the project pod's log shows.

I couldn't reproduce this anywhere except in the one place where it originally happened, and then it went away on doing a clean restart of the project. Hmm. Logically the bug itself makes absolutely no sense to me, at least in the current version of the code.

Close this if we don't see it again in a bit.
