I'm pretty sure this is a bug but then again I'm no expert and I've been unable to find many people who've experienced it. Basically when I applied a mirror to an object and moved the object the mirrored object moved in the same direction. Normally the mirror would move in the opposite direction i.e moving object up z axis would cause the mirror to move down the z axis instead of up as the original object.

This all started when I joined a circle to an object which was being mirrored. The circle was joined but the mirror modifier was automatically removed. From this point on no matter if I reloaded the startup file, reverted back to default settings or rebooted the PC the mirrored object would always move in the same direction hence why I think it's a bug rather than a setting I've mistakenly applied.

I fixed this unexpectedly by adding an object, adding the mirror modifier then applying it. After this I tried adding another mirror modifier and it worked as originally intended. To make sure it wasn't a fluke I restarted blender added a mirror modifier to a new object and it's working as expected.

The question is: Was this a temporary situation or does it happen to you more often? We need to be able to recreate this to fix it, so it's important that we are able to recreate.

Hi,

This has only happended to me once and I assumed it was a bug as I found a post from another user on a different site experiencing the exact same issue. Unfortunately, I've not been able to recreate the issue so it may be a one off, however, this affected blender entirely as in even new projects were affected by it not just the one I was working on at the time it occured.

I will try and to recreate on the same file and get back to you if it happens again.

Regards

I've found what the issue was and it's not a bug so apologies for flagging this as one. I was in object mode when I was moving the object around which appears to move the mirror and object at the same time and I didn't think to check in edit mode. Newbie mistake.

Please close this and thank you for your prompt response.

Ah yes, in Object Mode the Origin which is used to determine the mirror axis is transformed together with the object.

Anyway, thanks for the report :)
