I'm mining Unobtanium on tompool.org at block 452875 and at the same time at unobtanium.miners-point.com at block 456586. With "very" different difficulty for the same coin.
How comes ?
Please ELI5, because I'm new

Hello,
Please read https://bitcointalk.org/index.php?topic=527500.msg7601154#msg7601154
All pools need to upgrade to 0.9.5 or they will be on the wrong fork.
I've reached out to every pool I can find, in many different ways. Please help by asking your pool operator if he has upgraded to 0.9.5
PM me if you know of a pool not listed in the OP. I want to keep an an accurate list of known Uno pools.
