It seems that some people end up on a rogue chain after the update, please verify your block number with the number at the RIGHT BOTTOM of the explorer page: http://explorer.helix-crypto.com/

If your wallet is at different block, check your wallet if you're running the newest wallet version(https://github.com/ProjectHelixCoin/helix/releases). If you are, shut down your wallet -> go to your data folder (where your wallet.dat is) -> Remove folder "blocks" and "chainstate" and use our bootstrap file to sync up:

https://www.dropbox.com/s/5ni158xdf0nibef/bootstrap.dat?dl=1

Instead of starting your wallet after deleting the "blocks" and "chainstate" folder, put the bootstrap.dat in the same folder as your wallet.dat is in. Now launch your wallet and it should tell you "importing blocks from disk". Now simply wait till it finishes and verify your block count again with the explorer count.

For those who used the masternode script (https://github.com/ProjectHelixCoin/vps) and also have to resync those:

Get the bootstrap on this location ~/bootstrap.dat:
sudo apt-get install wget
cd ~/
wget https://www.dropbox.com/s/5ni158xdf0nibef/bootstrap.dat?dl=1
mv bootstrap.dat\?dl\=1 bootstrap.dat
sudo chmod +x ./bootstrap.dat
Stop your masternodes:
systemctl stop helix_n*
Then delete your blocks and chainstate folders:
sudo rm -r /var/lib/masternodes/helix*/blocks
sudo rm -r /var/lib/masternodes/helix*/chainstate
After removing the folders, copy the bootstrap to all MN locations (commands on that link):
https://pastebin.com/4Am36VDp
(to big to paste here, use the amount of masternodes you have)

Now start your masternodes again:
sudo /usr/local/bin/activate_masternodes_helix
(If it gives a single mn error, start it seperately via "systemctl restart helix_n<your nr>")
Now wait till they are synced up again and then start them via your controller wallet

Those who used this vps script: https://github.com/ProjectHelixCoin/Masternode-Setup-Helix

Stop your mn
helix-cli stop
Remove the blocks and chainstate folders
sudo rm -r ~/.helix/blocks
sudo rm -r ~/.helix/chainstate
Get the bootstrap on this location ~/bootstrap.dat:
sudo apt-get install wget
cd ~/
wget https://www.dropbox.com/s/5ni158xdf0nibef/bootstrap.dat?dl=1
mv bootstrap.dat\?dl\=1 bootstrap.dat
sudo chmod +x ./bootstrap.dat
Restart your wallet and let it sync up
helixd -daemon
Wait for your wallet to be synced
helix-cli getblockcount
Once synced, start your masternodes in your controller wallet
