Sorry for the long wait on this issue, which we do take seriously! Unfortunately as mentioned above we have extremely limited resources for Mutect2 maintenance at the moment due to our focus on Mutect3, which we see as the long-term solution to this and other issues. You should definitely continue to run 4.1.8.0 until this is resolved, if at all possible.
