[Q&A] Wrong Bootlader upgrade

Hi,
I've made a huge mistake :
I upgrade my moto g 4g peregrine phone (european version so I guess XT1039) with a XT1032 bootloader from 41.13 to 41.18.
I don't have any problem with the phone which seems to be working fine (I just can't install the last cyanogen rom).
What should I do, try to install the XT1039 bootloader 41.18 version ?

Thanks you for advices and any help
