Hi, I had a build fail with the error message below and would like some help troubleshooting it since it seems to be an internal NCrunch error message. The tests are being run from TeamCity using NCrunch Console v3.18.0.2. Re-running the build fixed the issue, but obviously it would be better if it didn't fail in the first place. Here's what seems like the relevant excerpt from the TeamCity log, please let me know if there's any other info you'd like to help with troubleshooting it. It seems like after the failure it went on to run the rest of the tests without issue. Code:
