Since I don't use Abounded Bases, I can't tell for sure. I will ask @nivex if he have some thoughts about this, but when I fixed reported errors in API (which AB calls), I tested it and it was accurate.
If you really want to investigate, try to set "Log Level (Debug, Info, Warning, Error, Off)": "Debug" and do dome stuff like claim the raid, placing TC etc. I need exact scenario, so I could reproduce it on my server, then I will be able to fix it.
