I've merged an important patch to database/version3. This fixes a address history/balance tracking concurrency bug that can lead to lost entries. There is also an unrelated concurrency patch that fixes undefined behavior in the case of reads during a block pop (reorg) where the reorg affects entries in the hash table collision list (other than the first entry). Many thanks to Suvorov Ivan [https://github.com/magisterRab] for reporting and helping to resolve this issue! I'll be porting these fixes to master. In the mean time please update and resync v3 community servers.
