There was a big spike in hashrate some days ago to over 10 TH and this raised the difficulty for XRC to an all time high. The hashrate was falling soon to normal levels and therefore we see VERY long times to find a block. Normal is 10min to find a block, now its 1-2 hours... This is very likely the reason for your experience.
BTW: Who on this world has 10TH free hashrate for the rare algo X13??? My only guess is its the manufacturer baikal itself.
That's correct explanation. Next difficulty retarget is in 1340 blocks.
BTW, please consider to to leave your vote if you want to see XRC listed on CCTIP
