So..... I was thinking, my M4 Manix needed a good clean and lube (you know where this is going, right..?)

Came apart easily. Everything cleaned and nice application of Nano Oil I put the spring and backspacer back on, attached the pivot and washer, reinstalled the blade, second washer, slid the second scale back into place and replaced the pivot screw and remaining two scale screws

Everything seemed to be fine but after assembly there is some side to side blade play.... When closed, the blade moves almost from one scale to the other. 1/2 open the blade feels loose on the pivot. Open, it's not bad if the lock is engaged but if I pull it back you can feel the wobble.

What did I do wrong?
