Hi! I have made many greenhouses and have never had an issue with them working. I built one into an already existing hole in a mountain and no matter what I did it would not give the greenhouse buffer. So I built a super basic 5x5 out of dirt with glass on the top and it is still not registering as a greenhouse. I am using slabs of glass but the flat sides are oriented inward. I am wondering if maybe it is a mod I have installed that could be messing it up? I am using the 1.22 version. Thanks
