recursive function has some problem?

Hi, thanks for your implementation,

I was interested in order preserved encryption,
and trying pyope and your rust implementation.

I wanted to validate the performance, so I tried to encrypt 1 ~ 1000,
however I noticed encrypted some output falls into same ciphertxt,
which gave me ladder-like output instead of linear one when I plot plaintxt vs ciphertxt.

for example, encrypting
[120:130]
resulted in [8388606, 8388606, 8388605, 8388605, 8388606, 8388605, 8388605, 8388605, 8388605, 8388605]

any thoughts??

thank you ahead,
