Ok so… First of all, that filp is expected - with a roll of 180°, that bone has to “face down”. This is expected behavior.

However, we had a nasty bug in code, which was generating that 'instability' of rolling - stupid really! fix incoming.

@Daniel Salazar (zanqdo), I didn't do anything here, you kudos can go to @Bastien Montagne (mont29) entirely ;D
