I’m still stuck on the oscillation in the Brio & Wu shock tube. It seems like it might be an issue with the method/limiters not working for MHD rather than them having a bug since this page in the FLASH user guide mentions something similar. However, a new limiter didn’t solve the issue. I’m going to try a more comprehensive rewrite soon to match Athena++ and see if that fixes the issue.
