Bug/Issue Literally cant slot replicator addons into the replicator

Hello, i've been enjoying Starbound non-stop since its release but suddenly ran into an issue. The replicator does not accept a single one of its addons, it is literally impossible to slot either three of them into it. I've tried everything i can think of - nothing is working. I even had to go to the wiki and get the fact the replicator is "end-game" crafting stuff spoiled for me in search of an answer. Is my game just bugged?

 

The add-on is a table itself, but has to be placed over the old one, like so: http://imgur.com/a/kDmz4

 

Got the same problem : try to make some room above of the replicator - I had some wooden platform that did get in the way and i could'nt add the addon.
By cleaning the area above i was able to put the addon.
