We decided to change the position of superblocks to avoid sync problems.
Old logic:2000%(when blocks are multiples of 3), 300%(except for above) after 30000 blocks

New logic:2000%(when 333blocks every 1000 blocks) such as 45333~45666、46333~46666、47333~47666,300%(except for above)  after 45000 blocks

We have already released new wallet accommpanied with this change.
Please be sure to download and use this new wallet to be adapted for new sequence of super blocks after reaching 45000 blocks.
If you continue to use old wallet,it probably cannot be synchronized with other nodes after 45000 blocks. So please download and use new wallet as soon as possible!
The Vesion of new wallet is 2.0.0
Please download the wallet for your OS from the link below.
