I've heard a few times in my recent return to collecting that there was an infamous fire at some Takara facility (or something like that) that resulted in the loss of some very key molds, thus greatly reducing the odds of them ever being reissued. I've tried to find more info at the wiki unsuccessfully. Can anyone point me in the right direction for more info and/or identify which molds are reputed to have been lost?

I've heard (among others I can't recall) that the Dinobots and G1 Devastator are lost.
