Retop symmetry problem is ruining my work

ZBrush Usage Questions
#1

Im on a deadline so excuse me for my aggressive attitude.
Im currently making an alien model (alien from the movies “alien”) and Im about to throw this computer and this piece of software out of the window because I’ve been doing retopology for 2 days straight.

The problem is that the edit retopology tool isn’t fully symmetric. When I delete a verticle on one side of the model - even WITH x-symmetry on - it’s not deleted from the other side sometimes. This has made me retop the entire back and belly of the model over, and over and over again. I keep getting assymetrical holes in the mesh on one side even as I have a lot of verticles covering that actual area - AND even as the verticles are symmetrical.

What the heck should I do? And don’t say smart resym because we all know it’s bugged and doesn’t work all the time.

EDIT: Another question:
Once Im finished with the retopology (which I am soon - just gonna have to fix this holes) and you create the new mesh - Is there any way you can analyse the mesh so you know its fully symmetrical? Like is there an analyze button somewhere?

I’m no expert whatsoever but when I’ve been having problems with things not working in z3 like I think they should I’ve found exporting the model on highest subd as an object out and importing it into Z2 solves some problems. This worked for me with unifying my mesh which just wouldn’t work in Z3 and getting a useable displacement map and avoiding exploding meshes again something in Z3 I just couldnt get to work properly. Maybe in Z2 it will Resym your mesh properly. I’ll keep my fingers crossed for you.

I have the exact same problem using zb4 retopo is not symmetrical only when moving points around is it symmetrical it will only delete and create points on one side or the other, not sure why anyone resolve this yet?

The way I handle re-symm is I do all symmetry in TopoGun on one side of the model, export that low rez model to Max, zero-X the centerline, copy and weld on centerline, import back into TopoGun and then generate my Sub-D, and finally back to Z. Works pretty well.

when you export at highest LOD and bring it back into ZB dont you loose all your history from LOD history? is there a way to do this export workaround and retain your LODs?
