I just enchanted a God Sword yesterday, and noticed no issues. Is the sword issue still occuring for you?
Additionally, I suspect the Depth Strider issue could be attributed to the fact that some 1.8 mechanics simply didn't get converted when Onis updated. One example is this: If you go into single player 1.8.x and use a sponge, you will see it behaves in a very different way than a sponge on MeepCraft does, which has behaved as sponges always have.
I will inquire about any relevant information on this issue though, and report any findings I get. Thanks for the report.
