Can't snapshot a VM with additional drives.

I am trying to get TrueNAS working in a VM. I have installed it in a VM and it was working fine, I verified that I could take snapshots of it too and it worked without any issues. But as soon I added some drives to the VM, I could no longer take snapshots. (added them by-id according to the wiki). Everything else was working, except for my missing ability to make snapshots.

"The current guest configuration does not support taking new snapshots"

I have tried unticking the "Backup" box in advanced options for all the drives (except where VM's OS is installed). I was hoping that would simply not include the drives in the snapshot, but that did not do anything so I am assuming that has to do with something else.

When I am removing the drives however, (tried just uncommenting them from the VM's config /etc/pve/qemu-server/200.conf), it instantly brings back my ability to snapshot (only tried with the VM turned off). I guess I could write a script that turns off the VM, removes the drives, takes a snapshot, adds the drives back and turns on the VM again, it does seem a bit stupid tho and it feels like there should be a tick for exactly that.

I am missing something ?
