I just had a kobo miner summoned from my deck by a kobo summoner. The miner entered play with 3 strength and 1 health. The turn prior, I had a kobo miner with exactly those stats taken under. Is it possible that stats don't reset under these circumstances?
Here is another -- rather minor and infrequent, but it did throw me for a second. I was playing Bulldog and played a pulsar opposite his fire giant. I then cast bodyswap giving the pulsar 3/4. Bulldog played narrow tunnels reducing the pulsar to 0/4. On my turn, the pulsar moved to a random column (with no auras or opposing minions). It continued to display stats of 0/4, although when I attacked for the turn, it did three damage and corrected the stats to 3/4.
I guess you can count on me to discover really obscure stuff!
These kind of errors are generally caused by a connection issue , where it loses the bit of information that should've caused an immediate update. We've seen similar when Game Center is really crowded. However, I will make a note of this particular one just in case.
