Now I know I'm not crazy.
I have my FW on a Virtualbox VM with an Immutable disk, last time I was on site I tried updating to 2.5.0 and something went wrong, it froze, so I manually restarted it, the thing is, it seems I forgot to set the drive to Immutable time ago, but it still stayed at 2.4.5_p1 after the update failed.
Time went by and last week I started having VPN issues. I've logged in to check, and it was updated to 2.5.1!
I had to get an image when it was 2.4.4 set to update to the DEPRECATED channel, updated to 2.4.5_p1 and set it to immutable. Let's see what happens.
