This is the second time this has happen. It only affect the specific safe file I'm playing. I have made 20 or so completed Genetic Templets with all 13 various samples. Then for no apparent reason I can no longer combine the Genetic Templet and a new Gene Sample on the crafting table. It doesn't matter if I try to craft just one or up to 9. It just wont give me an output item with a Genetic templet with the gene sample attributes. Nothing shows up in the output. Similar to the way banned items work on multiplayer servers. But this is a single player game and no items are banned. I double checked the banned items cfg to be sure. Nothing there.

I loaded up another single player game and I can build them there with no problem.

I even loaded up a backup of the game Im having the problem with from yesterday when I KNOW it worked and I still can't build them.

I recreated my game by making a new game with the same seed. Then from my glitched game I copied over only the "region" data to the new game which includes all data on buildings and map stuff but no character data. It still will NOT work and I can't combine a genetic template with a gene sample.

I am playing the Tekkit Legends Mod pack. I tried updating to the newest version of gendustry but then I got an error loading saying I needed a newer version of forestry, so i got that, then I tried loading it and got an error saying I needed a newer version of forge. So i got that and then I was stuck. It keeps saying I need a newer version of forge though as far as I know I have it and its installed correctly. (but maybe not).

The point is I can't build templates. would rather not start over as it will just happen again. Can't figure out, assuming its even possible, how to update the mods to a newer version or even if that would fix the problem.

I'm in desperate need of help.

Does anything show up in the logs when you do this?

Also can you try making a fresh template (with nothing in it) and combining the sample with it? Does that work?

dont know how to check logs. did try fresh everything and still wouldn't work. Again it only affects this one game. Not my other saved games.

I'm closing this issue as part of a spring cleaning of my issue trackers from old stuff.

If you believe it's a bug that is still relevant in Minecraft 1.12 - Feel free to reopen it.
