A while ago, you explained that, in order to make a certain item (Sigix Containement Pod) have dialogue, you made them a robot that looked like an item that only turned into an item after the dialogue.
This explained some things i'd noticed in the past (Sensor Array detecting the SCP, Phasing AFG not working), and honestly most things kind of make sense, even if they end up being inconsistent.
The issue is that the Sigix Containement Pod can be killed.
Normally, this can't happen without the player trying to do exactly this, like i did (see attached screenshot),
but the Core Cannon makes it possible for players to do that accidentally : It deals enough damage to blast through the door, making it ideal for destroying it, but since it has a penetration chance of unlimited, firing it directly into the center of the door would make it also hit the SCP, and from my testing with a Helical Railgun, i'm pretty sure it would one-shot the Sigix (unless you already accounted for that and they have enough thermal resistance to survive).
(Not very important but i find it funny : Using item dropping mechanics, i managed to get a golem into the chamber, who killed the Sigix (after i broke the barrier with an ST) because their "robot form" is neutral, which assembled attack.)
