# Consensus Group Crash Loops and Block Sync Fixes

### Summary​

In a previous release, we attempted to resolve some rare issues with consensus members forgetting they're in the consensus group. Unfortunately this traded a rare consensus member failure for a rare crash loop. This issue led to the long block over the weekend and we've been testing a fix for the last couple days.

Additionally it was observed that nodes with clock skew behind the block time would refuse to sync. This has also been corrected and validarted to unstick such nodes.

Additionally we've landed a bugfix for a rare division by 0 during PoC packet construction and bumped the assume-valid block to 211438.

### Plan​

We've been betaing this 2020.02.18.1 release overnight and plan to roll it out to general availability shortly.
