I think I've found the bug, but I need a little more info to confirm it.

Are you using a forwad() before the t_relay()?
Maybe some missing break after a forward() or route()?

If not, could you send me your config (privately)?

If I'm right about the missing break, then adding it would be the quick fix
(until I commit the "real" fix).
