Are you sure this is a fork-specific issue? Please ensure that Mihon does not replicate the same behavior before making an issue in this particular fork. If Mihon can also replicate this issue, you should close this and create an issue instead with Mihon, as any changes made with Mihon will be merged into this fork.
