Can you check that all fonts you use are part of the unity project. The labels have no name for me which might suggest that you depend on a system font not present for me.
Great to hear FONTFIX works, and HOTFIX lets you place Extractors (it was broken on compilation/builds). Shoving is a oversight that's been in all versions so far (Sorry). I'm trying to come up with an elegant solution to it that doesn't require the player to place props apart with minimum distance.
