I am not able to interact with the spawner peripheral, not sure when this became an issue, but might be while ago.

Have the same issue at other spawners, with which I have interacted before (one of them is spawning iron golems, so I'm quite sure :)

PS: We're still on 1.19.2 ofcourse

if i'm not mistaken, the 1.19.2 version has a block called Spawner Interface that is needed to do interactions with the spawner

Ohhh yes that changed!
