Hi - this is something I'm having a problem with too, with a couple of mods, namely Colored Workshop Lights and Eli's Craftable Flower Pots. For comparison, Old World Plaids works fine. The preview transforms don't show up, but bizarrely the items can be built, you just can't see them and they don't appear in game. Googling comes up with this thread as the top result, annoyingly! If anyone has any ideas, anything it might be as a functionality issue, please. I'm on vanilla, and for CWL I'm using 1.7a rather than 1.8 which requires Wasteland Workshop. Thanks
