This transaction verification fails on your node for some reason. This causes the block to be rejected, but the entire network has accepted this block as valid and is continuing to build on it. Something is odd here. I'm trying right now to get the block data from my node, "getblock 0000000000000000371fcf07810c3ac1b9c17daa5ddc9710dea32158d3f75665 false", but all it does is cause my cpu to run at 100%.

EDIT: Took about 7 minutes to get the raw block

EDIT: Here is the raw block, try "submitblock "
