No problem, modding in this game is honestly so fun. I think Cultist would be a perfect unit when the stomach system is finished, but for now they might be too advanced.
Oh also I forgot to explain why having the: "[Connection]Body, Twin" was the issue. I'm thinking it's because this type of connection can and will only digest simultaneously. Since the first tentacle is tied to her body they essentially act as two halves of one stomach that must be digesting at once or else none of them can, which creates the softlock. And the other tentacles are also tied to each other which makes them and extension of this rule.
