any hatch, been having trouble opening a bunch of them, the ones i use are mainly sandstone, flotsam and insulated. i’m suspecting the way they’re targetted when you “use” them. the sandstone ones installed with a 1 storey ladder seem particularly jammed up, which never happened before unless i was blocking it. not a huge deal, once i can finally get them to open i just disable the auto-close, or otherwise just remove them completely.
