I was hosting a server for a few friends of mine with approx. 70 mod loaded(with libs(also why don't modders package dependencies with their main jar?)). We played a few sessions then a power failure happened to my server computer. It loaded just fine but we quickly noticed that all non-vanilla blocks changed to another modded block. I also noticed that the original blocks and end product blocks are generally from the same mod so i figure block ids somehow got shifted by one index or two. Also this change didn't affect our inventories.
Is there any way to unshift these blocks, as we had some really great builds in progress. Thank you in advance!
