Can't sync the new wallet. Deleted all in roaming folder apart from my wallet.dat and am stuck at block 138608 and the debug log states:
Yeah, it's normal. your wallet is trying to force PoS blocks on its own that are invalid.
You should rename your wallet.DAT to something else, remove anything else, sync and then restoring your wallet.DAT
Hope this helps

and if anything let me know.
This should calm down in some days as mentioned above by Onefixt:
In order to transition to PoS-only mode, the latest wallet update changed the staking rules. The immediate effect is more transactions trying to stake at the same time, resulting in more orphan blocks - a situation similar to early mining on a PoW coin with low difficulty. This should calm down by itself in the next 4-5 days.
The checkpoint warnings, on the other hand, are due to constant attacks on the WATER network because of its low PoW difficulty. The wallet is actually performing perfectly - it stops creating new transactions when it detects a problem with the blockchain, thus protecting users - and exchanges - from losing coins. Once the network security is improved by transitioning to purely PoS operation, these checkpoint warnings will also become much less frequent.
