@ Steven SaxtonYesterday I noticed that the SLG network seemed a bit odd. My usual number of connections is 17-20, but I was only getting 4-5, and my computer seemed to be labouring a bit. Also, my stake weight was incredibly high compared to the network stake weight.
I checked the block explorer and, sure enough, the block height was different from that which was displayed on my wallet.
I assumed that I had forked and was now on another chain, so I attempted to re-sync using the zip file supplied by your good self a few days ago.
I synced fully in no time at all, without problems. I then checked the block height, which matched.

Currently staking normally.

My only concern is that, whilst on the other chain, I still managed to get 5 or so connections. Does this mean that other people are also forked?
Sterling Sentinel I noticed that yesterday also and I did find one wallet that was following it, unfortunately.
I have spoke to one other person earlier today on telegram that was in the fork. They corrected promptly also, which is greatly appreciated of you both.
It does seem others could still be in the fork but they are, and are being helped to, get on the proper chain. I will continue to investigate to find the 1 or 2 that still may be.
