Slave Objects, I think I'm going to cry.

I remeshed my columns for my contest entry. Now I want them to link together. I've been trying and trying and trying to get them to connect. But I am just thwarted at each turn!

I have a single story column as my repository. I have a 2 story that I need to link to it. Currently, I've recolored its original master to achieve the desired effect because it is still linked to that one. NO MATTER WHAT I DO. I also have various other 'broken' column pieces that were cloned from another completely free column. Remeshed those and I want to link them to the original 1 story version. Those don't work AT ALL. I don't know WHERE they are getting their texture from currently, happily though, it looks fine. When I try to connect them to repository object one of two things happens. Either the game loads and they appear flashing blue in the neighborhood (haven't chanced going farther than that) or they crash my game entirely.

I don't know what to do anymore.
